In the Presence of Oxygen, the Three-Carbon Compound Pyruvate Can

Multiple Choice

In the presence of oxygen, the three-carbon compound pyruvate can be catabolised in the citric acid cycle. First, however, the pyruvate (1) loses a carbon, which is given off as a molecule of CO₂, (2) is oxidised to form a two-carbon compound called acetate, and (3) is bonded to coenzyme A. Which of the following sets of products result from these reactions?

A) acetyl CoA, O₂, and ATP
B) acetyl CoA, FADH₂, and CO₂
C) acetyl CoA, NADH, and CO₂
D) acetyl CoA, NAD⁺, ATP, and CO₂
