Answer

In pyruvate oxidation, an acetate molecule and carbon dioxide are bound to coenzyme A to form acetyl coenzyme A, or acetyl CoA. Acetyl CoA is tasked with donating its acetyl group to the four-carbon compound oxaloacetate. This begins the citric acid cycle, the next step of cellular respiration.
