Respiration is an oxidation process exhibited by living organism in which complex organic compound decompose into carbon-dioxide and water for the production of energy
The process of respiration is shown by following equation:
Types Of Respiration
When respiration occurs in the presence of free oxygen, it is called aerobic respiration. Food material is completely oxidized in this process into CO2 and water and large amount of energy is released.
C6H12O6 + 6O2 —-> 6CO2 + 6H2O + 673 Kilo Calorie
When respiration takes place in the absence of oxygen then it is known as anaerobic respiration. In this process incomplete oxidation of food material takes place and produce carbon-dioxide and ethyl alcohol. Because of incomplete oxidation very low amount of energy is produced in it.
