In the human body, energy is primarily produced through cellular respiration, a process that converts nutrients from food into adenosine triphosphate (ATP), the energy currency of cells. This occurs mainly in the mitochondria, where glucose and oxygen are metabolized to generate ATP, carbon dioxide, and water. The energy stored in ATP fuels various biological processes, including muscle contraction, nerve impulse transmission, and metabolic reactions. Essentially, the body transforms chemical energy from food into a usable form through a series of biochemical reactions.
