Through which ATP-generating mechanism can long-lasting muscle contractions be sustained?

Question

Quizplus · Accepted Answer

Long-lasting muscle contractions require sustained ATP generation, which is most efficiently achieved through oxidative catabolism (also known as aerobic metabolism) in the presence of oxygen. This process produces a large amount of ATP and allows for sustained muscle contractions. Glycolysis and the creatine phosphate reaction are faster-acting ATP-generating mechanisms, but they cannot sustain long-lasting muscle contractions. Anaerobic catabolism can generate ATP quickly, but it also produces lactic acid and can only sustain contractions for a short period of time.
