Answer:
net gain is 2 ATP
Explanation:
It is the fermentation that usually happens in yeast. Like fermentation with lactic acid, alcoholic fermentation allows glycolysis to continue by ensuring that NADH returns to its oxidized state (NAD +).
Fermentation produces 4 molecules of ATP per molecule of glucose, compared with 38 by aerobic respiration. Since 2 molecules of ATP are used in glycolysis, the net yield for fermentation is 2 ATP.
