Pyruvate is the end product of glycolysis, which is converted into acetyl coA that enters the Krebs cycle when there is sufficient oxygen available. When the oxygen is insufficient, is broken down anaerobically, creating lactate in animals (including humans) and ethanol in plants.
In eukaryotic cells, pyruvate is transported to the mitochondrial matrix, where the Krebs cycle takes place. Before entering the Krebs cycle, the three-carbon pyruvate is oxidized to a two-carbon acetate molecule and carbon dioxide, producing one molecule of NADH.The acetate joins to a molecule of coenzyme A to form acetyl coenzyme A, which carries the acetyl group to the Krebs cycle.efore entering the Krebs cycle, the three-carbon pyruvate is oxidized to a two-carbon acetate molecule and carbon dioxide, producing one molecule of NADH.
