The major disadvantage of the glycolytic system for supplying ATP to muscle fibers is

Question

Quizplus · Accepted Answer

The two major disadvantages of the glycolytic system are that it is less efficient at producing ATP (compared to aerobic respiration) and that it leads to the accumulation of lactic acid. Choice A is true because the glycolytic pathway only produces two ATP molecules per glucose molecule, while aerobic respiration can produce up to 36 ATP molecules per glucose molecule. Choice C is true because when glycolysis occurs under anaerobic conditions, pyruvate is converted to lactate, which can build up and cause muscle fatigue. Therefore, D is the best choice.
