Respiration

The process by which food is oxidized to produce energy is called respiration. All living beings respire in order to produce energy which is utilized for carrying our various activities. Respiration is of two types, viz. aerobic and anaerobic. Aerobic respiration happens in presence of oxygen and complete oxidation of food takes place. In case of anaerobic respiration, the oxidation of food is not complete. Most of the organisms use aerobic respiration, while some organisms show anaerobic respiration. Anaerobic respiration also helps in carrying out fermentation which is utilized to produce wine and bakery products.
