A man goes swimming in a pond. As he swims, which reaction provides energy to power his muscles?
ATP regenerates from ADP using energy in glucose.
The ADP molecule adds a phosphate group and produces ATP.
ATP loses one phosphate group and converts to ADP.

The answer is ATP loses one phosphate group and converts to ADP.
ATP stores potential energy in the form of chemical bond. By breaking this bond and removing one phosphate group from ATP, which is then converted to ADP, great amount of energy is released and it is ready to be used.
