Question

Quizplus · Accepted Answer

The absence of mitochondria in certain muscle cells means that these cells cannot undergo oxidative phosphorylation, the process by which mitochondria generate ATP from glucose and oxygen. Instead, they rely on anaerobic glycolysis to generate ATP. This process produces lactic acid as a byproduct, which can accumulate in the muscles following exercise. Therefore, option A is the best choice. Options B and C are incorrect because carbon dioxide and oxygen are not directly related to the absence of mitochondria in the muscle cells. Option D is incorrect because muscle cells can still undergo glycolysis, even in the absence of mitochondria.
