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 uses water, sunlight, and carbon dioxide from the atmosphere to create glucose molecules, and releases oxygen as a by-product. Cellular respiration uses glucose molecules and oxygen to produce ATP molecules and carbon dioxide as the by-product. Photosynthesis takes place only when there is sunlight. Cellular respiration occurs at all times. Photosynthesis involves conversion of one type of energy into another: light energy into chemical energy. Cellular respiration involves using that chemical energy and breaking it down to release energy.
