Cellular respiration is a process by which cells harvest the energy stored in food. It includes glycolysis, the citric acid cycle, and electron transport. The three processes of ATP production or celluar respiration include glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation.
Controlled oxidation in a living cell is called respiration. By this process, energy is used for cell growth and building new tissues. It is the opposite of photosynthesis. Respiration occurs in all life forms and in all cellsRespiration occurs in all life forms and in all cells.
