Pyruvate, the product of glycolysis under aerobic conditions, is a metabolic branch point. As a preliminary to following the central path of aerobic metabolism from glycolysis to the citric acid cycle, we put pyruvate in perspective by considering its various possible fates. We also consider the broader context of common carboxylation and decarboxylation reactions in biochemistry. The most important fate of pyruvate at least for our present purposes is its oxidative decarboxyl… WebJun 18, 2024 · Discuss oxidative decarboxylation. Solution: Glycolysis results in the formation of two molecules of pyruvic acid, NADH, and ATP. It occurs in the cytosol of the cell.
