Question

What two chemical mechanisms change pyruvate to acetyl-CoA in the pyruvate dehydrogenase complex? Group of answer choices a) Decarboxylation and condensation. b) Oxidation and decarboxylation. c) Condensation and dehydrogenation. d) Condensation and oxidation. e) Dehydrogenation and oxidation.

Answer 1

Answer: B

Explanation:

Oxidation step

In the presence of oxygen, acetyl CoA delivers its acetyl group to a four carbon molecules, oxaloacetate to form citrate

Decarboxylation occurs when carboxyl group is removed to release carbon dioxide, NAD is reduces to NADH in this process
