What is the function of the enzyme pyruvate dehydrogenase in cellular metabolism?

A To convert pyruvate to lactate
B To convert pyruvate to acetyl-CoA
C To convert acetyl-CoA to pyruvate
D To convert lactate to pyruvate
Pyruvate dehydrogenase is an enzyme that catalyzes the conversion of pyruvate to acetyl-CoA, which is then fed into the citric acid cycle. This reaction is a critical step in the aerobic metabolism of glucose.
