Answer:
The production of ATP takes place due to the dissociation of the fuel molecules, that is, the fats, carbohydrates, and proteins. At the time of physical activity, three distinct procedures function to break apart the molecules of ATP. These are contraction, production of force, and eventually sports performance.
The by-product of the long-term system is carbon dioxide, ATP, and water. In order to exercise for a longer duration, a spontaneous supply of ATP must be accessible. A small concentration of ATP is present in the muscle, however, will provide energy for some seconds only.
The long-term system or the tendency to run at top speed for a distance generates energy via aerobic pathways. At the time of exercise, all the systems function correspondingly to a distinct extent, on the basis of the demand of the energy.
This system is dominant at lesser intensities and efforts withstands longer than two to three minutes. The generation of ATP or energy takes place in the mitochondria of the muscle fibers.
Mitochondria comprise unique enzymes, which allow for the dissociation of fuels via association with oxygen to generate huge quantities of energy. Thus, training the aerobic system enhances the size and number of the mitochondria, thus, producing the muscles more effective at utilizing oxygen for fuel.
