Cellular respiration<span> is </span>the process<span> of oxidizing food molecules, like glucose, to carbon dioxide and water.

Cellular respiration may be defined as the process of the metabolic reactions occurs in the cell of the organism that convert the energy in the form of ATP (adenosine triphosphate). The catabolic respiration reaction breaks the large molecules into simpler substances and energy is released in the form of ATP.
The heat is released in case of cellular respiration and considered as exothermic reaction. The substance get oxidize and reduce in sequential steps in case of the cellular respiration. Cellular respiration can occur in the presence of oxygen as well as in the absence of oxygen. Glycolysis, citric acid cycle and electron transport chain is included in cellular respiration.
