During exercise, stored chemical energy is converted to energy that can be used for muscle movement.
Best answer choice is:
A. muscle movement
Muscles use the stored energy of food we tend to eat and convert that to heat and K.E. The supply of energy that's used to power the movement of contraction in operating muscles is termed adenosine triphosphate (ATP). The ATP is outlined because the body's organic chemistry way to store and transport energy.
However, ATP isn't kept to a good extent in cells. Therefore, once contraction starts, the creating of additional ATP should begin quickly.
