Question

Quizplus · Accepted Answer

Muscle cells primarily use the PCr-ATP energy system to obtain energy during high-intensity activities such as weightlifting or sprinting. This system relies on stored creatine phosphate (PCr) in the muscle cells, which can be rapidly broken down to produce ATP (adenosine triphosphate), the primary energy currency of the body. This allows for a quick burst of energy without the need for oxygen. The other choices (carbon dioxide, citrate, oxalic acid) are not directly involved in the production of energy in muscle cells.
