Cellular respiration refers to an array of reactions, which generates ATP. The process of cellular respiration utilizes glucose to generate the ATP that the body requires to do essential activities. Cellular respiration can be differentiated into three segments: glycolysis, the citric acid cycle and the electron transport chain.
The essential components involved in the process are glucose, ADP or adenosine diphosphate, NAD a coenzyme used in the oxidation-reduction reaction and the reducing agent NADH.
