Question

Quizplus · Accepted Answer

When a person performs intense physical exercise, the muscles may experience a lack of oxygen, leading to the anaerobic breakdown of glucose to produce energy. This process produces lactate, which is associated with the burning pain felt in the muscles when fatigue sets in. The muscles respond to this situation by synthesizing more lactate, which can be used as an additional source of energy. Therefore, choice A) lactate is the best answer. The other options (glucose, citric acid, fatty acids, and galactate) are not directly implicated in this process.
