Two net molecules of ATP per fermentation cycle.
The first step of fermentation is glycolysis, which produces a net gain of 2 molecules of ATP. Fermentation produces no additional ATP.

Fermentation of one molecule of glucose produces 2 molecules of ATP per glucose molecule.

Fermentation does not directly cost ATP; in fact, it produces a small amount of ATP through substrate-level phosphorylation. However, fermentation does not generate as much ATP compared to aerobic respiration.
During lactic acid fermentation, 2 ATP molecules are produced per glucose molecule metabolized. This process does not require oxygen and is commonly used by muscle cells during strenuous exercise to generate energy quickly.
Fermentation does not produce ATP molecules during cellular respiration. Instead, fermentation occurs in the absence of oxygen to regenerate NAD+ for glycolysis to continue. This process does not directly generate ATP.

Cellular respiration is more efficient than fermentation. Cellular respiration produces approximately 36-38 ATP molecules, while fermentation produces only 2 ATP, which is a significant loss in usable energy.
