|Î0| Finally, the two PEPs ' transfer their phosphates to ADP, forming two ATPs and two molecules of pyruvate.

From every glucose molecule, glycolysis nets two molecules of ATP and two molecules of the electron carrier NADH. Two molecules of pyruvate are produced.

of two molecules of NAD+ to two molecules of NADH + H+ for each molecule of glucose.

Glycolysis can be divided into two stages: energy-investing reactions that use ATP, and energy-harvesting reactions that produce ATP (Figure 7.7).
