Which of the following is a vital role of phosphorus in the body?

Phosphorus plays a crucial role in assisting the body in energy utilization. It is a key component of adenosine triphosphate (ATP), which is the primary energy carrier in all living cells. Through its involvement in ATP production, phosphorus is essential for the processes that convert nutrients into usable energy forms. This energy is vital for various cellular functions, muscle contraction, and overall metabolic activities.

While phosphorus does contribute to other bodily functions, such as bone formation alongside calcium and aiding in cellular repair, its primary role in energy metabolism is why it is considered vital in the context of this question.
