Adenosine Triphosphate (atp)
Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration , and fermentation. All living things use ATP. In addition to being used as an energy source, it is also used in signal transduction pathways for cell communication and is incorporated into deoxyribonucleic acid (DNA) during DNA synthesis. This is a structural diagram of ATP. It is made up of the molecule adenosine (which itself is made up of adenine and a ribose sugar) and three phosphate groups. It is soluble in water and has a high energy content due to having two phosphoanhydride bonds connecting the three phosphate groups. ATP is the main carrier of energy that is used for all cellular activities. When ATP is hydrolyzed and converted to adenosine diphosphate (ADP), energy is released. The removal of one phosphate group releases 7.3 kilocalories per mole, or 30.6 kilojoules per mole, under standard conditions. This energy powers all reactions that take place inside the cell. ADP can also be converted back into ATP so that the energy is available for other cellular reactions. ATP is produced through several different methods. Photophosphorylation is a method specific to plants and cyanobacteria. It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration , which requires oxygen, or anaerobic respiration , which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen. Ana Continue reading >>

What is the difference between ADP and ATP? This is a pretty sophisticated question. ATPis short for "adenosine triphosphate" whichmeans there's one adenosine 3 phosphates in thismolecule. I'm guessing that you know that ATPis basically a way for the cells of your body tostore energy. To make things a little simpler,think of ATP as having 4 parts: the A (adenosine)and 3 P's (the phosphates). The energy is notstored in the A or the P's, but in the BONDSbetween the molecules. An ATP is kind of likea charged battery. When you take off one P, youget adenosine diphosphate or ADP (which isan A and 2 P's) plus an extra P. You also releasea bunch of energy that can be used by the cell todo work. So an ADP is like a battery that has lostsome of its charge. You can take off another Pand get adenosine monophosphate (AMP) andanother spare P, but your body usually uses AMPfor sending signals, so let's ignore that. Thereare pictures of these molecules at: Actually they're not true pictures because ATPis way too small to see, but they are models thatshow how we think they are put together. ATP is a sort of "universal power source"that allows your body to take the energy frompizza, carrots, or milk and turn it all into thesame type of energy. It's sort of like the way weuse electricity for most of our power needs eventhough the energy was once in the form of coal,water behind a dam, the inside of an atom, orsomething else. You wouldn't want to shovel coalinto your calculator. In the same way, it'seasier for all your cell's systems to use the samekind of power: ATP. Where does almost all of the energy on Earthcome from? ATP is a molecule with a lot of chemicalenergy. ATP stands for Adenosine Tri Phosphate, andthatthird phosphate is bonded to the other two with avery high energy bond, s Continue reading >>
Role Of Glucose In Cellular Respiration
This lesson is on the role of glucose in cellular respiration. In this lesson, we'll explain what cellular respiration is and what we need to start with to get the end products. We'll specifically look at the importance of glucose in this process. What Is Cellular Respiration? Sugar is everywhere in our world, from packaged foods in our diet, like tomato sauce, to homemade baked goods, like pies. In fact, sugar is even the main molecule in fruits and vegetables. The simplest form of sugar is called glucose. Glucose is getting a bad rap lately and many people are cutting sugar out from their diet entirely. However, glucose is the main molecule our bodies use for energy and we cannot survive without it. The process of using glucose to make energy is called cellular respiration. The reactants, or what we start with, in cellular respiration are glucose and oxygen. We get oxygen from breathing in air. Our bodies do cellular respiration to make energy, which is stored as ATP, and carbon dioxide. Carbon dioxide is a waste product, meaning our bodies don't want it, so we get rid of it through exhaling. To start the process of cellular respiration, we need to get glucose into our cells. The first step is to eat a carbohydrate-rich food, made of glucose. Let's say we eat a cookie. That cookie travels through our digestive system, where it is broken down and absorbed into the blood. The glucose then travels to our cells, where it is let inside. Once inside, the cells use various enzymes, or small proteins that speed up chemical reactions, to change glucose into different molecules. The goal of this process is to release the energy stored in the bonds of atoms that make up glucose. Let's examine each of the steps in cellular respiration next. Steps of Cellular Respiration There are Continue reading >>
Atp And Biological Energy
Adenosinetriphosphate (ATP) , the energy currency orcoin of the cell pictured in Figfures 1 and 2, transfers energy fromchemical bonds to endergonic (energy absorbing) reactions within the cell. Structurally, ATPconsists of the adenine nucleotide ( ribose sugar, adenine base, and phosphate group,PO4-2) plus two other phosphategroups. Figure 1. A 2-D stick view of the structure of ATP. The above drawing of ATP is from EcoCyc at Figure 2. A cartoon and space-filling view of ATP. Image from Purves et al., Life: The Science of Biology, 4th Edition, by Sinauer Associates ( www.sinauer.com ) and WH Freeman ( www.whfreeman.com ), used with permission. Energy is stored in the covalentbonds between phosphates, with thegreatest amount of energy (approximately 7 kcal/mole) in the bondbetween the second and third phosphate groups. This covalent bond isknown as a pyrophosphate bond. We can write the chemical reaction for theformation of ATP as: a) in chemicalese: ADP + Pi + energy ---->ATP b) in English: Adenosine diphosphate +inorganic Phosphate + energy produces Adenosine Triphosphate The chemical formula for the expenditure/releaseof ATP energy can be written as: a) in chemicalese: ATP ----> ADP + energy +Pi b) in English Adenosine Triphosphateproduces Adenosine diphosphate + energy + inorganic Phosphate An analogy between ATP and rechargeable batteriesis appropriate. The batteries are used, giving up their potentialenergy until it has all been converted into kinetic energy andheat/unusable energy. Recharged batteries (into which energy has beenput) can be used only after the input of additional energy.Thus, ATP is the higher energy form (the recharged battery) while ADPis the lower energy form (the used battery). When the terminal(third) phosphate is cut loose, ATP becomes ADP Continue reading >>
Similarities Between Combustion & Cellular Respiration
Similarities Between Combustion & Cellular Respiration By Micah McDunnigan; Updated April 25, 2017 Engines need energy to move. This is true whether you are talking about the internal combustion engines that power most cars or the processes that power organic life forms. Internal combustion engines get their energy through the process of combustion, while organisms get their energy through a process called cellular respiration. The two processes are very similar in nature. Both cellular respiration and combustion require a core fuel for the process to happen at all. This fuel is stored energy, and the entire process of combustion or respiration is to convert that energy from its stored state -- in the fuel -- to another state that the engine, either mechanical or bionic, can use to power its other operations. While fossil fuels and sugar molecules have very different structures, they both have a series of molecular bonds that the energy harvesting process will break apart. While breaking apart the bonds to release the stored energy from the fuels -- either fossil fuels for combustion or sugars for respiration -- the bonds will not break themselves apart. In each case, a catalyst is required to start the reaction that will break the bonds apart. In the case of combustion, the catalyst is a spark. Fossil fuels are flammable, so the spark will ignite the fuel in a cylinder, breaking apart the bonds and releasing the energy. For respiration, enzymes are used to break the sugar molecule apart. After the bonds for the fuel are broken, the energy being released needs to be transported to the part of the "engine" where it will be used. For internal combustion engines, the force of the explosion pushes on a piston, which translates the force of the explosion into mechanical ene Continue reading >>
Difference Between Glucose And Atp
Compare and Discern the Clear Difference Between Any Similar Things Home Difference Between Glucose and ATP Glucose and ATP are organic compounds composed of carbon, hydrogen and oxygen. Other than these three elements, ATP contains Phosphorus and Nitrogen. Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules. Glucose is a simple sugar which is widely used in living organisms. The chemical formula of glucose is C6H12O6. It is a monosaccharide which functions as a precursor for many carbohydrates found in the organisms. In plants, glucose is produced by photosynthesis and used as a substrate for energy production. In animals, glucose is a prime energy source. In prokaryotes , glucose subjects to either aerobic respiration, anaerobic respiration , or fermentation and converts into energy molecules. Therefore, glucose can be considered as one of a primary energy source of living organisms. Glucose is broken down completely to water and carbon dioxide by aerobic respiration. It starts with glycolysis and going via Krebs cycle and electron transport chain. In the end, it converts the energy in the nutrient glucose into 38 ATP and other two waste products. Anaerobic respiration produces less number of ATP from a glucose molecule since glucose is undergoing incomplete combustion. Some microorganisms ferment lactose to lactic acid or alcohol produce energy under anoxic conditions. All these processes use glucose as the starting substrate for ATP production.

Cell Energy And Cell Functions
Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first place? And how do they use it in the most efficient manner possible? Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight. In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1). Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow necessities to enter the house, various proteins that span the cell membrane permit specific molecules into the cell, although they may require some energy input to accomplish this task (Figure 2). Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it bu Continue reading >>

Thus, ATP has the most stored energy and AMP has the least amount of stored energy. ATP is the main energy source for most cellular functions. ATP is created during cellular respiration in the mitochondria of eukaryotic cells. During cellular respiration, the sugar called glucose (C6H12O6) and oxygen gas (O2) is converted into carbon dioxide gas (CO2), water (H2O), and ATP. The energy within ATP is released in order to perform everyday cellular functions as phosphates are removed. Continue reading >>

After completing this tutorial, you will be able to complete the following: Write the equation for lactic acid fermentation. Write the equation for ethyl alcohol fermentation. Write the equation for cellular respiration. List the similarities between cellular respiration and fermentation. List the differences between cellular respiration and fermentation. ~ The two types of respiration are fermentation and cellular respiration. How are fermentation and cellular respiration alike? ~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use. How are fermentation and cellular respiration different? ~ Fermentation and cellular respiration differ in that fermentation does not require oxygen while cellular respiration does. Fermentation and cellular respiration are also different because water molecules are not produced during fermentation but are produced during cellular respiration. All fermentation reactions occur in the cell's cytoplasm but during cellular respiration, only glycolysis occurs in the cytoplasm. Lastly, fermentation produces a net gain of 2 ATPs while cellular respiration produces a net gain of 32 ATPs. What causes muscle pain in our bodies after we exert ourselves? ~ As we exert ourselves, our cells may begin to run out of oxygen. As a result, our cells begin fermentation, which allows them to continue to produce ATP. This results in the production of lactic acid in our muscle cells. The accumulation of lactic acid is what causes muscle tenderness. Continue reading >>

( Learn how and when to remove this template message ) Adenosine triphosphate (ATP) is a complex organic chemical that participates in many processes. Found in all forms of life, ATP is often referred to as the "molecular unit of currency " of intracellular energy transfer . [1] When consumed in metabolic processes, it converts to either the di- or monophosphates, respectively ADP and AMP . Other processes regenerate ATP such that the human body recycles its own body weight equivalent in ATP each day. [2] It is also a precursor to DNA and RNA. From the perspective of biochemistry , ATP is classified as a nucleoside triphosphate , which indicates that it consists of three components, a nitrogenous base ( adenine ), the sugar ribose, and the triphosphate. It is used in cells as a coenzyme . In terms of its structure, ATP consists of an adenine attached by the 9-nitrogen atom to the 1 carbon atom of a sugar ( ribose ), which in turn is attached at the 5 carbon atom of the sugar to a triphosphate group. In its many reactions related to metabolism, the adenine and sugar groups remain unchanged, but the triphosphate is converted to di- and monophosphate, giving respectively the derivatives ADP and AMP . The three phosphoryl groups are referred to as the alpha (), beta (), and, for the terminal phosphate, gamma (). In neutral solutio Continue reading >>
Atp Synthesis And Storage
Go to: Introduction Within cells, energy is provided by oxidation of “metabolic fuels” such as carbohydrates, lipids, and proteins. It is then used to sustain energy-dependent processes, such as the synthesis of macromolecules, muscle contraction, active ion transport, or thermogenesis. The oxidation process results in free energy production that can be stored in phosphoanhydrine “high-energy bonds” within molecules such as nucleoside diphosphate and nucleoside triphosphate (i.e., adenosine 5′ diphosphate and adenosine 5′ trisphosphate, ADP, and ATP, respectively), phosphoenolpyruvate, carbamoyl phosphate, 2,3-bisphosphoglycerate, and other phosphagens like phosphoarginine, or phosphocreatine. Among them, ATP is the effective central link—the exchange coin—between energy-producing and the energy-demanding processes that effectively involve formation, hydrolysis, or transfer of the terminal phosphate group. In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP. In the first process, when glucose is converted into pyruvate, the amount of ATP produced is low. Subsequently, pyruvate is converted to acetyl coenzyme A (acetyl-CoA) which enters the TCA cycle, enabling the production of NADH. Finally, NADH is used by the respiratory chain complexes to generate a proton gradient across the inner mitochondrial membrane, necessary for the production of large amounts of ATP by mitochondrial ATP synthase. In addition, it should be mentioned that acetyl-CoA can be generated also by lipid and protein catabolism. The aim of this work is to provide an overview of the principles governin Continue reading >>

Would you like to merge this question into it? already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? Answers.com is making the world better one answer at a time. ATP and glucose are similar because they are both chemical sources of energy used by cells. They are very different in terms of composition and structure. Glucose is made up of carbon, hydrogen and oxygen only whereas ATP has phosphorus and nitrogen in addition to the aforementioned three elements. Also, glucose is different from ATP in that the glucose does not have an aromatic ring even if it has a six membered cyclic ring. The conversion of the energy in glucose to ATP is more efficient than the conversion of the energy in gasoline to the movement of a car. The difference is the key to the way in which living things store energy. ATP and Glucose are similar in the fact that they are used by cells (microscopic organisms inside all living things) for energy. Glucose is like food for cells, it is where they get there nutrients. When we eat food, like a sandwich, the sandwich gets broken down in our stomachs, and glucose (form of sugar from the food) enters our blood stream. Then it is used for the cells. ATP is a form of energy that is created by the cell itself. It has the same effect on the cell, but is easier to obtain. (MORE) Continue reading >>
