Animals use respiration to make energy.Respiration is a process in living organisms which involves the production of energy usually with intake of oxygen and the release of carbon dioxide.Animals mostly use aerobic respiration in which oxygen is required for the process. It is summarized in the word equation:Glucose + Oxygen → Energy +Carbon dioxide + waterGlucose is broken down by use of oxygen to release energy with carbon dioxide and water as by-products. Approximately 2,900 kJ of energy are released when one molecule of glucose is broken down. The released energy is used to make a special energy molecule called Adenosine triphosphate or ATP. ATP is the form in which this energy is temporarily kept in the cell. It is only made when needed and is used up almost immediately.
