Which of the bioenergetics pathways commences immediately upon the onset of physical activity and produces energy quickly?
a. oxidative pathway
b. aerobic pathway
c. glycolysis pathway
d. ATP-CP pathway
Answer: d. ATP-CP pathway
The ATP-CP pathway commences immediately upon the onset of physical activity and quickly results in energy. This pathway provides energy for short durations, and therefore is ideal for quick and powerful bursts of intense activity.
ATP-CP system (phosphagen system) is used only for short durations. This system neither uses oxygen nor produces lactic acid if oxygen is unavailable and is thus said to be alactic anaerobic. This is the primary system behind very short, powerful movements.
