Cellular respiration requires energy from an organic source, such as glucose and oxygen, to take place. Cellular respiration is the process by which energy is harvested from an organic source and then stored in the form of ATP to later carry out reactions in the cell. Without the organic source of energy, the reactions cannot take place. Oxygen is needed to serve as the final electron acceptor in electron transport.
During cellular respiration, oxygen and glucose are used to create the useful product ATP. ATP is a usable form of energy that cells use, and it can be transported to any cell in the body. The by-products carbon dioxide and water are also created during cellular respiration. Carbon dioxide is disposed of through exhalation while water is excreted from the body through urine or sweat.
