Answer:
Aerobic respiration provide muscles with ATP to perform contraction and removes the lactic acid formed during anaerobic respiration.
Anaerobic respiration serves as instant energy source for muscle contraction during intense physical activities.
Step-by-step explanation:
Muscles need ATP for their contraction. Aerobic respiration provides muscles with a large amount of ATP for their contraction during any routine activity. It also removes the lactic acid formed during anaerobic respiration so that muscle's strength is not compromised.
Intense physical activity poses the need for a quick oxygen supply to sustain muscle contraction. Anaerobic respiration provides ATP for such muscle contraction as aerobic respiration is slow process.
