Detailed explanation-1: -Fermentation begins with glycolysis which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+.
Detailed explanation-2: -The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD+.
Detailed explanation-3: -Fermentation reactions reduce pyruvate with electrons from NADH to regenerate NAD+ (opposite of pyruvate oxidation).
Detailed explanation-4: -During NADH regeneration, the two NADH donate electrons and hydrogen atoms to the two pyruvate molecules, producing two lactate molecules and regenerating NAD+.
