Contrast complete glucose oxidation, lactate fermentation, and alcoholic fermentation.

Question

Quizplus · Accepted Answer

Lactate fermentation and alcoholic fermentation both produce 2 ATP molecules per glucose molecule, which is less than the approximately 30-32 ATP molecules produced by complete glucose oxidation. However, lactate fermentation produces lactic acid, not fructose, and alcoholic fermentation produces ethanol, making option D incorrect. Options A and B are also incorrect because glucose oxidation produces significantly more ATP than either fermentation process, and lactate fermentation is not the primary energy source for muscles during extended periods of work; muscles rely on aerobic respiration when oxygen is sufficient and switch to lactate fermentation only when oxygen is limited.
