Final answer:

The ATP-Phosphocreatine system supplies energy to muscles during intense activity lasting about 10 seconds.


Explanation:

The ATP-Phosphocreatine system supplies energy to muscles during intense activity lasting about 10 seconds. Creatine phosphate can provide energy for a short duration, typically up to 10-20 seconds, before other energy systems need to take over. This system is crucial for quick bursts of energy required during activities like sprinting.
