Explanation:
Detailed explanation-1: -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: -NAD+ can be regenerated in the cytoplasm from NADH through the conversion of pyruvate to lactate by the lactate dehydrogenase (LDH), thereby maintaining active aerobic glycolysis [5].
Detailed explanation-3: -The molecules of NAD+ are recycled back to glycolysis. The recycling of NAD+ allows glycolysis to continue.
