How Is Breathing Related to Cellular Respiration?

Cellular respiration is directly related to breathing, as breathing provides the necessary oxygen molecules for the process of cellular respiration to take place; cellular respiration is a process by which cells acquire energy. The oxygen provided by breathing is used as a final hydrogen acceptor for the process, explains

During inhaling, the oxygen necessary for cellular respiration is provided. During the exhale, the carbon dioxide that is produced by cellular respiration leaves the body. The relation between breathing and cellular respiration is critically important because without either one of the processes, the other cannot occur, reports Pearson Education.

To start the process, all that is necessary is glucose and oxygen. Oxygen, however, is not produced by the human body and thus needs to be acquired through breathing. Carbon dioxide and water are the two products of the process of cellular respiration, notes

During cellular respiration, cells acquire the energy that they need to carry out their tasks. This energy is produced by breaking down fuel molecules such as lipids, carbohydrates and fats, through oxidation. The energy produced through these oxidized molecules is stored in the form of adenosine triphosphate, abbreviated as ATP, explains For Dummies. Every cell depends on ATP for survival.
