A: Cells use energy in order to grow, regulate metabolism and reproduce. This energy is obtained from a source such as food molecules or light from the sun, and through processes like glycolysis, the citric acid cycle and oxidative phosphorylation, an energy-rich molecule is then created.
Instead they use a molecule called Adenosine triphosphate (ATP) to keep themselves going. The cells, therefore, must have a way to take the chemical energy stored in food and transform it into the ATP they need to function. The process cells undergo to make this change is called cellular respiration.
