Respiration

n. act of breathing; making breathe, ventilating

Respiration is a term used in both biochemistry and physiology.In the case of biochemistry it refers to : Respiration, the release of energy from glucose or other organic substances inside living cells. Every cell needs to respire in order to produce the energy it needs. Cellular respiration is a often used to describe this phenomenon. See the following subjects : Cellular respiration, the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processesAnaerobic respiration, a process that allows respiration without use of oxygen; can only happen for a limited amount of time in humansPlant respiration, the enzymatic oxidation of substrates in plants, leading to the release of carbon dioxide
