Detailed explanation-1: -When glucose ferments, there is a net gain of two ATP molecules in the glycolysis process. Both lactic acid and alcoholic fermentation proceed in the same way. When a glucose molecule is partly oxidised to make two molecules of pyruvate, glycolysis produces four molecules of ATP.

Detailed explanation-2: -Pros and Cons of Fermentation Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose. Although fermentation produces less ATP, it has the advantage of doing so very quickly.

Detailed explanation-3: -Solution: The net gain of ATP for one molecule of glucose in fermentation is 2. Therefore, net gain of ATP for two molecules of glucose in fermentation is 2x2=4ATP.

Detailed explanation-4: -Lactic acid fermentation has two steps: glycolysis and NADH regeneration. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH.
