Answer:
Option B, 3 minutes
Step-by-step explanation:
It’s not the ATP only that provides energy for continuous 2-3 minutes but the system of ATP-PC where PC stands for phosphocreatine. The immediate energy requirement is fulfilled by breaking down high energy phosphate molecule and thus energy for short exercises of duration 15 seconds can be obtained instantly.
After the usage of ATP, enzymes break down PC to provide energy for further few seconds and also provide energy for ADP and pi to join and form more ATP. This new ATP can further break down and provide more energy. In this way this ATP –PC system provides energy for 2-3 minutes.
Hence, option B is correct
