Question

Quizplus · Accepted Answer

Oxygen is required for cellular respiration, which is the process by which cells convert food into energy. Without a constant supply of oxygen, the body cannot efficiently produce the energy needed for survival. While water, carbon dioxide, iron, and vitamins are all important for overall health, they are not directly involved in the energy production process in the same way that oxygen is.
