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.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
