Which enzyme is responsible for the conversion of pyruvate to acetyl-CoA, and what is the specific requirement for its activity?
- A.Pyruvate carboxylase requiring biotin
- B.Pyruvate dehydrogenase complex requiring NAD+ and CoA
- C.Pyruvate decarboxylase requiring TPP
- D.Pyruvate kinase requiring Mg2+
Show correct answer & step-by-step solution
Correct answer: B — Pyruvate dehydrogenase complex requiring NAD+ and CoA
Solution
- The reaction is .
- This reaction is catalyzed by the pyruvate dehydrogenase complex.
- The complex requires as an electron acceptor and as a substrate.
- Hence the answer is (B).
