Which of the following enzymes catalyzes the conversion of pyruvate to acetyl-CoA during cellular respiration?
A.D) Pyruvate Dehydrogenase
B.C) Citrate Synthase
C.B) Phosphofructokinase
D.A) Pyruvate Kinase
Explanation
Core Concept
Pyruvate Dehydrogenase is the enzyme that catalyzes the conversion of pyruvate to acetyl-CoA during cellular respiration. This reaction is a critical step in the process of aerobic respiration, as it allows for the transfer of electrons from pyruvate to NAD+, generating NADH.
