At the end of glycolysis, we’re left with two ATP \text{ATP} ATP A, T, P, two NADH \text{NADH} NADH N, A, D, H, and two pyruvate molecules. If oxygen is available, the pyruvate can be broken down (oxidized) all the way to carbon dioxide in cellular respiration, making many molecules of ATP \text{ATP} ATP A, T, P. read more
