Final answer:
The statement is false because the ATP and creatine phosphate system is designed for short bursts of activity and can only provide energy for about 8-10 seconds, after which the body switches to other energy systems for longer exercises.
Step-by-step explanation:
The energy system that uses ATP and creatine phosphate is specifically designed for short bursts of high-intensity activity, not for long exercise sessions. Creatine phosphate can supply the energy needs of a working muscle at a very high rate but only for approximately 8-10 seconds. After this period, the body must rely on other energy pathways, like the breakdown of glycogen to make ATP from glucose, to fuel longer activities.
Therefore, the statement 'The energy system that uses ATP and creatine phosphate fuels the body for long exercise sessions.' is false. The correct energy systems for longer durations involve aerobic pathways and slower energy-producing processes, which can sustain the required energy over extended periods of time, well beyond the brief window where creatine phosphate is effective.
