Detailed explanation-1: -The purpose is to convert NADH back into NAD+so that glycolysis can continue so that the cell can produce 2 ATP per glucose.
Detailed explanation-2: -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-3: -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-4: -NAD+ is limiting, and must be reformed to allow the continuation of the glycolytic degradation of glucose producing ATP.
Detailed explanation-5: -What is the function of fermentation? Fermentation enables cells to produce chemical energy from the breakdown of sugar, e.g. glucose, without the help of oxygen.
