Q. Acetyl CoA is produced from pyruvic acid by :

(a) Oxidative decarboxylation

(b) Oxidative phosphorylation

(c) Oxidative hydrogenation

(d) Oxidative photorespiration

Solution :

Correct option : A Acetyl CoA is produced from pyruvate by the process of oxidative decarboxylation in the presence of an enzyme called the pyruvate dehydrogenase complex (PDC). The by-products of this reaction are carbon dioxide and NADH. Thus, the correct answer is ‘oxidative decarboxylation.’
