Question Detail
Question
One of these enzymes is a multienzyme complex requiring five coenzymes for its reaction
Correct Answer
Option A is the correct answer.
Detailed Explanation
The pyruvate dehydrogenase complex (PDC) is a huge multienzyme complex that catalyzes the conversion of pyruvate to acetyl-CoA. It requires five coenzymes: thiamine pyrophosphate (TPP), lipoamide, coenzyme A (CoA), FAD, and NAD+. Lactate dehydrogenase is a simpler enzyme that does not form such a complex.
