Cellular respiration commences with a glucose molecule gradually broken down to give carbon dioxide and water with the production of some form of energy in ATP. Much more ATP is produced as the reactions proceed to oxidative phosphorylation.
Explanation: Cellular respiration involves the combustion of of food (stored in the form of sugar) which is glucose to produce energy in the form of Adenosine Triphosphate (ATP) - which is the energy current, along with the production of carbon dioxide all in the presence of oxygen - besides, it is combustion, so it involves the use of oxygen.
In essence, generally, it is simply the burning/combustion of glucose to produce energy in form of ATP.
