The pyruvate dehydrogenase complex and the $\alpha$-ketoglutarate dehydrogenase complex are homologous enzyme assemblies that require several different coenzymes to carry out their reactions. Which compound does NOT participate directly in the function of these complexes?

Question

Quizplus · Accepted Answer

Flavin mononucleotide (FMN) is a coenzyme that participates in the electron transport chain, but it does not directly participate in the function of the pyruvate dehydrogenase complex or the α-ketoglutarate dehydrogenase complex. Coenzyme A, lipoic acid, thiamine pyrophosphate, and nicotinamide adenine dinucleotide (NAD+) are all essential coenzymes for the activity of these complexes.
