Quizplus · Accepted Answer

Glycogen stored in the muscles is the next available energy source after ATP depletion. Glycogen can be quickly broken down into glucose, which can then be used for energy production through glycolysis. This is the primary energy source used during short high-intensity activities such as weightlifting, sprinting, and jumping.

Answer C can also be correct as fats are the primary energy source used during low-intensity, long-duration activities such as distance running or cycling. However, fats cannot be rapidly broken down for quick energy production and therefore take longer to be utilized compared to glycogen.
