Basics Of Metabolism

Voiceover: Let's talk about this thing called metabolism. I remember being told in medical school that metabolism was the sum total of all of the chemical reactions in the human body, but I never actually knnew what that meant. I like to think of metabolism as kind of like the balance in the body between the reactions that build things up, and another way of saying that is anabolism. On the other side of the scale, the reactions that break things down. The medical way of saying that is catabolism, or catabolism. So, metabolism is kind of the balance between building things up, or repairing or storing inside the body and breaking things down, usually for energy needs. How are the things that we eat broken down for energy or stored within the body? Let's start by looking at carbohydrates. So, we eat our carbohydrates, and they are in the form of starches or sugars, and we saw in our last video that those could get broken down into their kind of component parts. The major component, or the major single unit currency of carbohydrates is called glucose. That glucose, and this is very big-picture, can get broken down further into a compound called pyruvate. The pyruvate then gets broken Continue reading >>

    Triacylglycerol vs. Glucose

    Can somebody provide an explanation of why Triacylglycerols provide more ATP per carbon when fully oxidized to ATP than does Glucose. I'm thinking along the lines of B-Oxidation and such but I'm not too sure how the numbers work out. Thanks a lot!

    In order for a n-carbon fatty acid to be completely oxidized, (n/2)-1 turns of B-oxidation cycles must be completed, which produces (n/2)-1 FADH2, (n/2)-1 NADH, and n/2 acetyl-CoA. Each acetyle-CoA then goes through the citric acid cycle and produces the same amount of ATP as half a glucose. So as long as a fatty acid is 4 carbons or longer, it will produce more ATP than glucose.
    Also remember a triglyceride has three fatty acid chains and have chains usually around 16 carbons long in humans. So if you do the math, there are usually around 9x more ATP in triglycerides.

    This of course is unless information for the mcat... all you need to know is that triglycerides have more energy, but ATP are more usable energy sources by breaking the high energy phosphate bonds.

Basal cell carcinoma symptoms are related to basal cell cancer. It is types of skin cancer. This is a form of skin cancer. It starts off evolved in the basal cells, a sort of cell within the skin that makes new skin cells as older ones die off. Basal cell carcinoma symptoms often show as a bit obvious bump on the skin, even as it can get different types. Basal cell carcinoma occurs most people regularly on components of the pores and skin which might be uncovered to the sun, like as your neck and head. The primary causes of basal cell carcinoma are ultraviolet (UV) ray from the tanning bed or daylight. Even as ultraviolet rays knock our pores and skin, over the month, they're able to damage the DNA in our pores and skin cells. The DNA holds the code for the method the one's cells increase. Basal Cell Carcinoma Symptoms: Basal cell carcinoma typically will increase on solar-uncovered locations of your body, especially your neck and head. This skin most cancers show less frequently on the legs and trunk. Basal cell carcinoma hardly ever takes region on additives of your body commonly covered from the solar along with girls breasts or genitals. Approximately eighty-five percent of BCC

Cell Metabolism And Cancer Cell Metabolism

Home | Cancer Systems Biology | Targeting mutant p53 cancers | Cancer Cell Metabolism | Network Analysis | Human dynamics | Resources As with any living "organism", cancer cells require metabolism to sustain their existence. This include the support of several functions, including cell maintenance, proliferation, motility and the excretion of extracellular factors. Common to all this activities is the demand for energy, mainly in the form of ATP. Cells utilize two major pathways for energy generation, glycolysis and oxidative phosphorylation (OxPhos). Glycolysis converts glucose into pyruvate generating two molecules of ATP for each molecule of glucose. In human cells pyruvate can be converted to lactate, which is then excreted to the extracellular media. This pathway does not require oxygen and it is the default when cells are deprived from oxygen (hypoxia). OxPhos takes place in the mitochondria and can metabolize different substrates (e.g., pyruvate, fatty acids, amino acids) to generate ATP. For example, OxPhos generates 32 molecules of ATP per molecule of glucose. In contrast to glycolysis, OxPhos requires oxygen and can only occur its presence (normoxia). Given that OxPhos ha Continue reading >>

What is BASAL METABOLIC RATE? What does BASAL METABOLIC RATE mean? BASAL METABOLIC RATE meaning - BASAL METABOLIC RATE definition - BASAL METABOLIC RATE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(hkg)). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food). In bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) is used. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mamma

€¢ Several Principles Govern Metabolic Pathways:

Energy and Electrons from Glucose • The sugar glucose (C6H12O6) is the most common form of energy molecule. • Cells obtain energy from glucose by the chemical process of oxidation carried out through a series of metabolic pathways. • Metabolic pathways are formed by complex chemical transformations in the cell which occur in a number of separate reactions. • Each reaction in the pathway is catalyzed by a specific enzyme. • Metabolic pathways are similar in all organisms, from bacteria to humans. • Many metabolic pathways are compartmentalized in eukaryotes, with certain reactions occurring inside an organelle. • The operation of each metabolic pathway can be regulated by the activities of key enzymes. Cells trap free energy while metabolizing glucose • When burned in a flame, glucose releases heat, carbon dioxide, and water. • C6H12O6 + 6 O2 ( 6 CO2 + 6 H2O + energy (heat and light). • The same equation applies for the biological, metabolic use of glucose. This process, however, has many steps and is carefully controlled. • About one-third of the energy is collected in ATP. • ï„G for the complete conversion Continue reading >>
