What Makes Glucose In The Cell?

Share on facebook

In this video we discuss what is cellular respiration, and how the body converts food into energy. Transcript/Notes What is cellular respiration? Well cellular respiration is basically the breakdown of organic molecules such as carbohydrates, fats and amino acids, which make up proteins, to produce energy. Glucose, which is a simple carbohydrate, is the preferred source for the cellular respiratory pathway. In this video we are going to go through the basics of this process, we are not going to go through every single step in detail, rather a summary of the steps. There are four main stages that take place during the cellular respiratory pathway, glycolysis, an intermediate stage, the citric acid cycle and the electron transport system. An important thing to know is that glycolysis does not require oxygen making it anaerobic, and the other 3 stages do require oxygen, making them aerobic. So, lets say you eat a banana, which contains glucose. And your body wants to take some of that glucose and convert it to cellular energy. Inside the cytosol of a cell is where the first step, glycolysis, takes place. During glycolysis a molecule of glucose, which has 6 carbons, goes through a seri

Process by which a cell uses energy from sunlight to make food Organisms that make their own food such as plants Organism that cannot make its own food, photosynthesis creates food that heterotrophs can eat The organelle in plant cells that capture energy from the sun A structure or part that is enclosed within its own membrane inside a cell and has a particular function. Organelles are found only in eukaryotic cells and are absent from the cells of prokaryotes such as bacteria. Pigments are "molecules that absorb specific wavelengths (energies) of light and reflect all others." Pigments are colored chemical compounds: the color we see is the net effect of all the light reflecting back at us. The green pigment inside chloroplasts that absorb light from the sun. Chlorophyll and other pigments capture sunlight energy and uses it to power the second stage of photosynthesis to produce sugars Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals. These compounds are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1:2:1. CHO, is a carbohydra Continue reading >>

    So when a pt comes in with DKA I know that the pH is low due to the acidic ketone bodies and HCO3- gets low in an attempt to buffer and I can understand how initially the PCO2 is low. BUT for most questions I see, the stem usually refers to stating that the patient is lethargic ...so in that case wont the PCO2 be high due to hypoventilation?

  2. Convalaria

    lethargic is the state of consciousness. patient still can hyperventilate, namely DKA coma is characterized by Kussmaul breathing pattern: rapid and deep

Bbc Bitesize - Ks3 Biology - Respiration - Revision 1

is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation). Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Here is the word equation for aerobic respiration: glucose + oxygen carbon dioxide + water Energy is released in the reaction. The mitochondria , found in the cell cytoplasm, are where most respiration happens. During hard exercise, not enough oxygen can reach your muscle cells. So, aerobic respiration is replaced with anaerobic respiration . This does not need oxygen for it to happen. Here is the word equation for anaerobic respiration in humans: Anaerobic respiration produces much less energy than aerobic respiration. The waste product, lactic acid , builds up in the muscles causing pain and tiredness . This leads to cramp. Lactic acid is only broken down when you start aerobic respiration ag Continue reading >>

    So I went to the pharmacy yesterday to pick up a new scale and some Ketostix. The pharmacist (who works right next door to me and I've become friendly with) asked me if I was "starting some kind of crazy diet." I told him I've started a ketogenic diet and I'm just trying it out to see if it's right for me. He asked me a few questions about it, mostly about macro ratios and if it's been working so far. When I told him about the higher fat ratio (as opposed to high protein) he seemed somewhat intrigued, but still a little skeptical. The other pharmacist who was working with him chimed in at that point. He said apparently in some Scandinavian countries, they've found that a higher fat content and fewer simple carbs in a person's diet is ideal and actually recommended. However, they both agreed that ketosis for an extended period of time can be very hard on the kidneys. I did a little investigating on my own and there's very little info regarding the long-term effects of the high fat/moderate protein/low carb keto diet. So my question is, has anybody experienced any kidney issues on this diet? Has anyone received any similar warnings from their physician?
    TL;DR
    Pharmacist warned about kidney issues caused by long term ketosis. Seeking out facts/sources to prove or disprove this claim.

  2. cloudmind

    When I first started keto I ended up going to hospital because I had severe internal pain that wouldn't go away. Turns out I was eating far too much protein so my kidneys were giving me grief. Fixed it by upping the fat macros in my diet and I went back to being pain free. Hooray for butter and coconut oil!
    Given my experience, I can understand where the pharmacists are coming from since I think there might* have been a spate of people doing atkins-like diets with kidney problems in the past (too much protein, not enough fat).
    *rampant speculation on my part

  3. Prairie-dawg

    I don't blame them for that at all. In fact, before I really started doing my homework on keto, I used to internally roll my eyes when people would talk about low carb dieting. I think there's a lot of risidual negativity held over from the early days of Atkins regarding low carb diets. Fortunately, I'm always happy to have a teaching moment when the chance arises!

How Do Our Cells 'burn' Glucose To Produce Energy? - Quora

Answered Jan 28, 2017 Author has 239 answers and 397.1k answer views Your body needs glucose to obtain the energy to function. Glucose is obtained by the body through eating carbohydrates. In each gram of carbohydrates you consume there are four calories worth of energy. Once ingested into the body, special enzymes in the digestive system break down the carbohydrates you have eaten into simple sugars called glucose. This breaking down process allows the body to access the calories of energy contained in the carbohydrate. After eating a meal, the body goes to work to break down the carbohydrates to produce glucose. This glucose is released into the bloodstream, raising your blood sugar levels. For the cells to access the glucose in the bloodstream, your pancreas must produce a hormone called insulin. As your blood glucose levels start to rise, the pancreas is triggered to release insulin into the bloodstream. Without insulin the cells will be unable to absorb the glucose needed to obtain energy. Problems with insulin either occur because there is not enough insulin being produced by the body, or the cells have become resistant to insulin. These problems are symptoms of a disease ca Continue reading >>

    Does it knock you out of ketosis?

  2. peauk

    I'd say for me no. I started off drinking my usual 5 cups a day, and was in ketosis. I reduced it & I was drinking 1 cup a day & still in ketosis. I think it varies from person to person whether it causes your weight loss to stall.

  3. CarlG

    Maybe try a half and half mix of regular and decaf to see if that helps at all? I have 12 oz of that every day with good steady weight loss while still getting my morning ritual / boost.
