During aerobic respiration, glucose is oxidized to pyruvate, and then pyruvate is converted to acetyl CoA before entering the citric acid cycle. The conversion of pyruvate to acetyl CoA results in the production of one molecule of carbon dioxide. Therefore, one-third (1/3) of the carbon dioxide produced by aerobic respiration is generated by the oxidation of pyruvate to acetyl CoA.
