An athlete got exhausted as a result of an extensive workout. He was urged to take a break for a while and then return.
Explanation:
Answer (A): In the presence of oxygen, glucose is converted to ATP (adenosine triphosphate), which is required for muscular contraction. However, when the body cannot fulfill the oxygen requirement during strenuous activity, glucose undergoes metabolism without oxygen, resulting in the creation and accumulation of lactic acid. The accumulation of lactic acid in muscles causes weariness after running rapidly for a long time.
Answer (B): Resting allows the body to refuel, store energy, and mend damaged tissue. The body will continue to break down following intense activity if there isn't enough time to repair and refill it.
