Explanation:
Detailed explanation-1: -The ATP-CP pathway supplies about 10 seconds worth of energy and is used for short bursts of exercise, such as a 100-meter sprint. This pathway first uses up any ATP stored in the muscle (about 2 to 3 seconds worth). Then it uses creatine phosphate (CP) to recycle ATP until the CP runs out (another 6 to 8 seconds).
Detailed explanation-2: -There are three major energy systems which are responsible for the resynthesis of ATP (Figure 2). These systems can be categorised as follows: (1) The Phosphagen System, (2) The Glycolytic System, and (3) Mitochondrial Respiration.
