Please describe the aerobic respiration of an organic molecule such as glucose in one concise paragraph must use the terms: electron donor, electron acceptor, ATP. krebs cycle (TCA and citric acid cycle), proton motive force (proton gradient), oxidation, oxygen, glycolysis, reduction, electron transport chain, catabolic, mitochondria
PRE-KREBS/TRANSITION PHASE: In the absence of oxygen the luyunde molecules from glycolysis are converted to lactic acid. If oxygen is present, they are instead converted into 2 molecules of _which then enter the mitochondria to undergo anaerob metabolism. During this transition phase, no ATP is produced but are released. and Mitochoadrial CITRIC ACID CYCLE: The citric acid cycle occurs in the matrix Both of the molecules of Adel produced after glycolysis run through the citric acid cycle reactions. At the...
a. The metabolism of glucose by glycolysis to acetyl-coenzyme A, followed by the TCA cycle, releases CO2 molecules by oxidative decarboxylation reactions. Write down the oxidative decarboxylation reactions that result in CO2 production. Name the enzyme involved in each reaction and give the names and complete structures of all reactants and products. Only abbreviated names of enzyme cofactors are required. (b) From the steps drawn in part (a) above, how many total ATP molecules would be produced from oxidative phosphorylation?

In reaction 1 of the Krebs cycle, acetyl-CoA formed in the pyruvate dehydrogenase reaction condenses with the four-carbon compound to form with the elimination of coenzyme A. Since the product has three carboxyl groups, this pathway is referred to as the cycle. In reaction 2 of the Krebs cycle, this product then undergoes to form The enzyme is called aconitase because the compound cis-aconitate is a(n) of the reaction. Reaction 3 eliminates CO_2 to...
Select ALL of the statements that correctly describe the Krebs cycle. A. Pyruvic acid must be converted to acetyl CoA prior to entering the cycle B. The molecule oxaloacetic acid picks up the acetyl group from acetylCoA, and in the last step of the cycle, oxaloacetic acid is regenerated. C. Electrons removed during oxidation steps are picked up by NAD or FAD. D. Each turn of the cycle generates one ATP molecule for a total of two per molecule of...
From the information in Chapter 8 on metabolism and Appendix A, we can see the multiple metabolic pathways involved in generating ATP from the breakdown of the nutrients glucose, protein and fats. Glycolysis generates pyruvate, the pyruvate then becomes Acetyl CoA, which enters the Krebs Cycle (TCA), products of the Krebs Cycle then enter the Electron Transport Chain (ETC) where ATP is the final product. Fat breakdown (beta-oxidation) also generates Acetyl CoA, which then enters the Krebs Cycle to produce...
Please help fill in the blanks ! The end product of glycolysis is ____________________ . For every molecule of glucose, (how many?) _________ molecules of (A) is/are produced. For every molecule of glucose, (how many?) _________ molecules of ATP is/are produced (total, by substrate level phosphorylation)? (A) then enters an organelle known as a ____________________ . Once inside (B), (A) is converted into ___________________ which is a molecule composed of (how many?) _________ carbon atoms. (C) can then enter the ___________________ Cycle...

(2 point each; 34 points total) ADP lysosome oxidation phosphorylation NAD pyruvate plasma membrane oxidative phosphorylation acetyl CoA cytosol carbon dioxide nucleus NADH sucrose ubiquitination GTP electrons FADH2 reduction B-sheets matrix ATP FAD kinase vacuole H* mitochondria NADH inner membrane...
13) When a molecule of glucose gets split during the energy investment phase of glycolysis, the products are two molecules of that then move to the energy payoff phase. A) Glyceraldehyde-3-phospahte B) Pyruvate C) Acetyl-COA D) NADH 14) Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP. Most of the energy from the original glucose molecule...
