Detailed explanation-1: -Overview of pyruvate oxidation 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: -It produces energy, generated by the complete oxidation of acetyl CoA to carbon dioxide and water through the tricarboxylic acid cycle and oxidative phosphorylation.
Detailed explanation-3: -Metabolism of pyruvate results in the formation of acetyl coenzyme-A as the chief end product. In fermentation, pyruvate is reduced to produce lactic acid or ethanol.
Detailed explanation-4: -Pyruvate oxidation produces acetyl Coenzyme A, NADH, and carbon dioxide.
