Detailed explanation-1: -In the process of fermentation the NADH + H+ from glycolysis will be recycled back to NAD+ so that glycolysis can continue. In the process of glycolysis, NAD+ is reduced to form NADH + H+. If NAD+ is not present, glycolysis will not be able to continue.
Detailed explanation-2: -Lactic acid fermentation produces lactic acid and NAD+. The NAD+ cycles back to allow glycolysis to continue so more ATP is made.
Detailed explanation-3: -The only requirement for a fermentation reaction is that it uses a small organic compound as an electron acceptor for NADH and regenerates NAD+.
Detailed explanation-4: -Fermentation reactions reduce pyruvate with electrons from NADH to regenerate NAD+ (opposite of pyruvate oxidation).
Detailed explanation-5: -Fermentation removes electrons from NADH molecules and recycles NAD+ molecules for glycolysis. Why is this process important? Because glycolysis, just like cellular respiration, needs a molecule that picks up electrons. It needs molecules of NAD+.
