During glycolysis, what are the net products per glucose molecule?

Explanation:
Glycolysis breaks one glucose into two molecules of pyruvate in the cytosol, with an energy accounting that yields a net gain of two ATP. Two ATP are invested early, while four ATP are produced later, giving a net +2 ATP. During the process, NAD+ is reduced to NADH twice, so two NADH are formed. The end products are two pyruvate molecules. Lactate would only appear if pyruvate is converted to lactate in fermentation under anaerobic conditions; glycolysis itself produces pyruvate, not lactate. Therefore, the net products are two ATP, two NADH, and two pyruvate.
