Question

what molecule is produced by the oxidation of pyruvate and enters the krebs cycle? multiple choice acetyl-coa citrate carbon dioxide atp

Explanation:

In cellular respiration, after glycolysis, pyruvate is oxidized (in the pyruvate oxidation step) to produce acetyl - CoA, which then enters the Krebs cycle (also known as the citric acid cycle). Citrate is an intermediate in the Krebs cycle, not the molecule that enters from pyruvate oxidation. Carbon dioxide is a by - product of pyruvate oxidation and the Krebs cycle, not the molecule that enters the Krebs cycle from pyruvate oxidation. ATP is produced during cellular respiration but is not the molecule that enters the Krebs cycle from pyruvate oxidation.

Answer:

A. acetyl - CoA
