Detailed explanation-1: -Pyruvate-three carbons-is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A . A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.
Detailed explanation-2: -Answer and Explanation: Pyruvate oxidation produces acetyl Coenzyme A, NADH, and carbon dioxide.
Detailed explanation-3: -The reactants of pyruvate oxidation are as follows: Pyruvate: the end product of glycolysis.
Detailed explanation-4: -Reactants for pyruvate oxidation are pyruvate, NAD+, and coenzyme A (CoA). One TCA cycle requires acetyl-CoA, one ADP, three NAD+, and one FAD. Finally, oxidative phosphorylation and the electron transport chain use the reactants ADP, NADH, FADH2, and O2.
Detailed explanation-5: -During pyruvate oxidation, pyruvate is broken down into CO2 and an acetyl group.
