B
Water
C
Oxygen
D
Carbon dioxide
Verified step by step guidance1
Understand the process of pyruvate oxidation, which is a key step in cellular respiration where pyruvate is converted into acetyl-CoA.
Recognize that during pyruvate oxidation, pyruvate undergoes decarboxylation, which involves the removal of a carbon atom from pyruvate.
Identify that the removed carbon atom is released as carbon dioxide (CO₂), a byproduct of this reaction.
Note that this process also involves the reduction of NAD⁺ to NADH, but NADH is not removed from pyruvate; it is formed as a result of the reaction.
Conclude that the correct answer to what is removed from pyruvate during its conversion into an acetyl group is carbon dioxide (CO₂).
