Detailed explanation-1: -Fermentation follows glycolysis in the absence of oxygen. Alcoholic fermentation produces ethanol, carbon dioxide, and NAD+. Lactic acid fermentation produces lactic acid (lactate) and NAD+. The NAD+ cycles back to allow glycolysis to continue so more ATP is made.
Detailed explanation-2: -Without NAD+, cells cannot keep going through glycolysis, and ATP production stops. To solve this problem, cells convert NADH back into the election carrier, NAD+, through fermentation.
Detailed explanation-3: -Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.
