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: -Fermentation allows continued glycolysis by regenerating NAD+ from NADH.

Detailed explanation-3: -The products are lactate and NAD+. The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD+. Electrons from NADH and a proton are used to reduce pyruvate into lactate.

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: -Lactic Acid Fermentation The purpose is to convert NADH back into NAD+so that glycolysis can continue so that the cell can produce 2 ATP per glucose. Figure 1 Lactic acid fermentation is common in muscles that have become exhausted by use.
