Muscle pain during heavy exercise is most closely related to which process?
Answer and explanation
Correct answer: Anaerobic respiration during oxygen shortage and formation of lactic acid.
The governing concept is fermentation in muscle cells when oxygen supply cannot meet the increased demand. During intense exercise, muscles need ATP rapidly, and some glucose may be broken down anaerobically, producing lactic acid. Its temporary accumulation is associated with the burning sensation and pain during or after strenuous activity. Option A is correct; the remaining choices describe plant nutrition, digestion, or excretion.
