Answer:

The correct answer would be a. ATP-CP.

ATP-PC (adenosine triphosphate and phosphocreatine) system is the energy system which provides energy for short duration exercises which are completed in 10-15 seconds.

If the activity continues beyond 15 seconds the body switches to other energy systems such as the lactic acid system and aerobic system.

It takes almost 2-3 minutes to replenish the lost ATP and PC.

Few exercises which may rely on ATP-PC system are performing one rep max, sprinting for 50-100 meters, et cetera.

nekit [7.7K]
Not necessarily, the equilibrium does not necessarily mean that the partial pressures are equal-- to explain this, you could look up the equilibrium constant of partial pressures. They are ratios, and not just equal partial pressures!
