The reason for cells to carry out cellular respiration is because of releasing energy. Cellular respiration is metabolic processes and reactions that take place in cells of organisms and then convert biochemical energy which is from nutrients to adenosine triphosphate and releases wastes.

Respiration is termed as one of the key ways a cell may release chemical energy to fuel cellular activity. Cellular respiration is being considered an exothermic redox reaction which uses nutrients in respiration include fatty acids, amino acids, and sugar.
