Question

Quizplus · Accepted Answer

The conversion of pyruvate to acetyl CoA is an irreversible process as it is catalyzed by pyruvate dehydrogenase, which irreversibly removes a carboxyl group from pyruvate and forms acetyl CoA. Once acetyl CoA is formed, it can only be further oxidized via the Krebs cycle or used for biosynthesis, and cannot be converted back to pyruvate.
