- Match the name of the process with its description Electron transport chain oxidation of pyruvate chemiosmotic phosphorylation citric acid cycle 1. The 2-carbon acetyl group separates from coenzyme A and attaches to a four carbon molecule called oxaloacetate, forming the 6-carbon molecule called citrate. In a series of enzyme-catalyzed steps, the citrate loses 8 high-energy electrons to NAD+ and FAD. In addition, ADP is phosphorylated (changed to ATP) as part of step three. Carbons leave as carbon dioxide in steps 2 and 3. This leaves a 4-carbon molecule, which eventually combines with another Acetyl CoA to form citrate and the cycle begins again. 2. Pyruvate moves into the mitochondrion and two electrons are removed from pyruvate and transferred to NAD+. One of the carbon atoms in pyruvate leaves as a molecule of carbon dioxide. The remaining 2-carbon piece becomes attached to Coenzyme A. 3. Protons concentrated in the…arrow_forwardAll steps in the calculations must be reported, incomplete reporting of these leads directly to return. Make a theoretical calculation of how many ATP molecules can be formed from the degradation of an acetyl-CoA molecule to carbon dioxide and water if the entire proton gradient across the mitochondria's inner membrane can be used for ATP production and when the ATP synthase has 15 c-subunits.arrow_forward(a) A simplistic interpretation of the Q cycle would predict that the proton pumping efficiency of cytochrome bc1 would be reduced by no more than 50% in the presence of saturating amounts of antimycin A. Explain. (b) Indicate why cytochrome bc1 is nearly 100% inhibited by antimycin A.arrow_forward
- Explain in detail of the process of cellular respiration, including all the stages of cellular respiration (glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation) and explain the substrate and product of each pathway. And make a table of the products formed at the end of glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation (ATPs, NADHs, water, and carbon dioxide). Then discuss about oxidation-reduction of various molecules that are a part of these pathways.arrow_forwardCalculate the biochemical standard cell potential for the oxidation of NADH by molecular oxygen O2 + 2NADH + 2 H+ → 2H2O + 2NAD+arrow_forwardThnx in advancearrow_forward
