Which process is important for all life because it turns carbohydrates fats and proteins into energy that the body's cell can use?

The process important for all life that converts carbohydrates, fats, and proteins into usable energy for the body's cells is called cellular respiration. During this process, cells break down these macromolecules in the presence of oxygen to produce adenosine triphosphate (ATP), which serves as the primary energy currency of the cell. Cellular respiration occurs in several stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation, ensuring that energy is efficiently extracted and utilized.
