Questions
1. It showed that fermentation started to occur once the oxygen is gone, and the yeast will respire anaerobically. It is proven once it smelled like alcohol.
2. Aerobic respiration occurs in the presence of oxygen, CO2 and water are produced, and occur in plant and animal cells. In Aerobic respiration, glucose is broken down into CO2, H20 and ATP; more ATP is released (38). Anaerobic respiration happens in the presence of no oxygen and occurs in many anaerobic bacteria and in muscle cells. During this respiration, either lactic acid or alcohol is produced. Glucose is broken down into Lactic Acid and ATP; very little of it is released (2).
3. The mitochondria has an outer and inner membrane. Cristae are the folds of the inner membrane and the matrix is the cytoplasm of the mitochondria.
4. The increase in the number of cristae is significant because the increased surface area of reaction helps produce more ATPs.
5. ATP a molecule that stores all of the energy that comes from food.
6. The products of Glycolysis are a net gain of 2 ATPs and 2 NADHs. The next step becomes the Krebs cycle, which uses oxygen. Pyruvic acid is passed along into this stage and is broken down into CO2. NAD+ is converted into NADHs and FADH2s, which are high-energy electrons that can be used to create a large sum of ATP. From there, the Electron Transport Chain then converts the high-energy electrons into ATP and H2O.
7. The Krebs cycle occur in the matrix while ETC occurs in the inner membrane of the mitochondria.
8. Thirty six ATP molecules can be produced from one molecule of glucose.
9. There was a net gain of 2 ATP molecules in glycolysis.
10. There were 2 ATP molecules produced in the Krebs cycle.
11. There were a total of 36 ATP production in the ETC.
12. Pyruvate is half a glucose molecule.
13. Two pyruvates are produced from one glucose molecule.
14. The chemical formula of glucose is C6H12O6
15. The chemical formula of pyruvate is C3H6O3

    he Krebs Cycle also expressed as: CH3C(=O)C(=O)O− (pyruvate) + HSCoA + NAD+ → CH3C(=O)SCoA (acetyl-CoA) + NADH + CO2 is the main pathway in all aerobic organisms. Basically it’s the way that cells produce energy for itself, but the only issue is it requires the presence of oxygen. In total eight reactions that take place in the mitochondria, and these reactions result in two carbon molecules and oxidizes it into carbon dioxide. Step 1 Citrate synthase bridges to Oxaloacetate substrates which can then bind to Acetyl–CoA’s acetyl group, which drops off the A Co-enzyme. This in turn created citrates for usage later in the Krebs cycle. This six-carbon molecule will be degraded, and biotransformed back into Oxaloacetate.Step 2The citrate isn't…

    The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation, and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis, which also occurs in anaerobic respiration, and the pyruvate dehydrogenase complex, which occur in the cytoplasm and the mitochondrial matrix respectively. In aerobic respiration, glycolysis breaks down one molecule of glucose and two molecules of pyruvate, and gives a net product…

    Cellular respiration includes the processes of glycolysis, krebs cycle, and the electron transport chain. Glycolysis is used to convert glucose to produce two pyruvate as well as 4 ATP’s and 2 NADH but uses 2 ATP to have a net product of 2 ATP and 2 NADH. The krebs cycle converts pyruvate to Acetyl CoA, which produces 2 ATP,8 NADH, and 2 FADH’s per glucose molecule. Electron transport Chain is the last and most important step of cellular respiration, it makes ATP with the movement of electrons from high energy to low energy that makes a proton gradient which makes ATP, this cannot occur unless oxygen is present. Fermentation is an anaerobic process in which converts sugars into acids, alcohol, or alcohol. This process occurs in yeast and bacteria as well as muscle cells that have no oxygen left. In yeast fermentation produces ethyl alcohol and carbon dioxide from glucose and fructose. Fermentation in bacteria cells the process of fermentation produces ethanol, while in human muscle cells fermentation produces lactic acid in cells that have a short…

    ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP, NADH, and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not, enzymes are mediated in the cytoplasm. The electron transport chain, chemiosmosis, and aerobic respiration use NADH molecule (which it main purpose is to transport electrons form one molecule to another) for later purposes. The mitochondrial matrix receives pyruvate from the cytoplasm after it crosses over the mitochondrial membrane. When the pyruvate enters the Krebs cycle it goes through many stages of biochemical enzyme-catalyzed reactions. In more detail about the cycle its main purpose is to produce little amounts of ATP by removing carbon dioxide and hydrogen from pyruvate molecules. Within the inner membrane of the mitochondrion the electron transport chain and chemiosmosis synthesis ATP with hydrogen ions which are NADH and FADH2. The Krebs cycle and glycolysis produce less ATP because chemiosmosis synthesizes a great amount of ATP.…

    There are three stages of cellular respiration and these are, glycolysis, the krebs cycle and the electron transport chain (ETC). Glycolysis is the first step in a biomedical pathway of respiration. It occurs in the cells cytoplasm and no oxygen is needed for this. The next stage is the Krebs cycle, this takes place in the mitochondrial matrix and is a cycle of reactions. One ATP is created for every complete cycle and oxygen is needed for this. The last stage of cellular respiration is ETC, this also occurs in the mitochondrial matrix and the molecules are passed next along the ETC. Oxygen is also needed for this. Cellular respiration is an example of an catabolic reaction as it is the breakdown of larger molecules to Mooresville smaller ones.…

    The processes described so far – glycolysis followed by the link reaction, the Krebs cycle and the electron transport chain – make up the metabolic reactions that we call aerobic respiration. They can all only take place when oxygen is present. This is because oxygen is needed as the final electron acceptor from the electron transport chain. If there is no oxygen, then the electron carriers cannot pass on their electrons, so they cannot accept any more from reduced NAD.…

    This cycle also called the “Krebs cycle”, completes the breakdown of glucose all the way to CO2, one of the waste products off cellular respiration. The enzymes for the citric acid cycle are dissolved in the fluid within mitochondria. Glycolysis and the citric acid cycle generate a small amount of ATP directly. They generate much more ATP indirectly, via redox reactions that transfer electrons from fuel molecules to NAD+, forming NADH.…

    Anaerobic respiration refers to respiration without oxygen. A common example of this is swimming as there is no oxygen in water therefore the individual continues to move and exercise without oxygen. This causes oxygen debt which must be repaid once the anaerobic exercise is complete. This is why athletes who exercise in short bursts breathe heavily after. The equation of anaerobic exercise is:-…
