Question:
In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. First, however, the pyruvate 1) loses a carbon, which is given off as a molecule of CO2. 2) is oxidized to form a two-carbon compound called acetate, and 3) is bonded to coenzyme A.

These three steps result in the formation of
a. acetyl CoA, O2, and ATP.
b. acetyl CoA, FADH2, and CO2
c. acetyl CoA, FAD, H2, and CO2
d. acetyl CoA, NADH, H+, and CO2
e. acetyl CoA, NAD+, ATP, and CO2
Answer:
D: acetyl CoA, NADH, H+, and CO2
