Question

Quizplus · Accepted Answer

When oxygen is not available in sufficient amounts, the process of anaerobic respiration takes place, which involves the breakdown of glucose to generate energy in the absence of oxygen. The end product of anaerobic respiration in muscle cells is lactic acid, which can build up and cause fatigue and muscle soreness. This is why heavy exercise can be challenging for the body, especially when it comes to endurance activities that require sustained exertion. Therefore, the correct answer is D) lactic acid.
