<prompt> Which among the following is NOT a coenzyme of pyruvate dehydrogenase during the decarboxylation of pyruvate?FADNADFolic acidLipoate  <response>: Pyruvate is oxidatively decarboxylated by pyruvate dehydrogenase PDH complex, producing acetyl CoA, which is the major fuel for the tricarboxylic acid cycle. This multienzyme complex requires five coenzymes: Thiamine pyrophosphate Lipoic acid FAD NAD Coenzyme A Pyruvate dehydrogenase is inhibited by its products, acetyl-CoA, and NADH Ref: Biochemistry By Richard A.
