Detailed explanation-1: -In lactic acid fermentation, the 3-carbon pyruvate is converted to the 3-carbon lactic acid. Also NAD+ is regenerated in the process, allowing glycolysis to continue to make ATP in anaerobic conditions.
Detailed explanation-2: -Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid (C3H6O3) (see figure below) and regenerates NAD+ in the process, allowing glycolysis to continue to make ATP in low-oxygen conditions.
Detailed explanation-3: -The pyruvate oxidizes the NADH back to NAD+ by taking a hydrogen and two electrons from it. It then restructures some of its bonds, and turns into lactate; this process regenerates NAD+ so that glycolysis can continue. :) 10 comments.
Detailed explanation-4: -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-5: -Fermentation allows continued glycolysis by regenerating NAD+ from NADH. NAD+ is limiting, and must be reformed to allow the continuation of the glycolytic degradation of glucose producing ATP.
