3. Energy & Cell Processes

Each of the following describes the pyruvate oxidation reaction except that _____________________.

a) It connects glycolysis to the citric acid cycle.

b) Each pyruvate is converted to an acetyl-CoA molecule.

c) NAD⁺ is reduced to NADH.

d) This reaction occurs within the cytoplasm.

e) Carbon dioxide is released as a by-product.

In aerobic cellular respiration, pyruvate molecules must be transformed through a process called pyruvate oxidation before they can be broken down in the Krebs Cycle. What are the products of pyruvate oxidation?

a) Acetyl CoA, O₂, and ATP.

b) Acetyl and CO₂.

c) Acetyl CoA, FADH₂, and CO₂.

d) Acetyl CoA, NADH, and CO₂.

e) Acetyl CoA, NAD⁺, ATP, and CO₂.
