Question

Quizplus · Accepted Answer

Anaerobic pathways of ATP production are responsible for the quick bursts of energy required for rapid movements during intense physical activity, such as tennis. This pathway uses glucose as a fuel source and does not require oxygen, but it does produce lactic acid as a byproduct, which can cause fatigue and muscle soreness. This pathway can sustain energy production for several minutes before it becomes depleted. ATP and creatine phosphate reserves are used during the initial stages of exercise and are quickly utilized. Aerobic pathways of ATP production are not suitable for power movements and are used during endurance exercises. Slow-twitch cells are used for lower intensity activities such as jogging or walking.
