Key Points

Respiration is the process by which energy is released from food in our body. The function of the respiratory system is to breathe in oxygen for respiration producing energy from food and to breathe out carbon dioxide.
An important feature of all living cells is respiration which is related to the liberation of metabolic energy as ATP.
Respiration is an amphibolic and exergonic cellular process.
Respiration is of two types.
- Aerobic respiration- with the use of oxygen. Eg plants
- The equation of Aerobic Respiration
  - Glucose + Oxygen → Carbon dioxide + Water + Energy
- Anaerobic respiration- without the use of oxygen. Eg yeast
- The equation of Anaerobic Respiration
  - Glucose → Alcohol + Carbon dioxide + Energy

Various types of respiration are:

Respiratory organ	Types of respiration	Animals
Lungs	Pulmonary	Mammals, Birds, Reptiles, and amphibians
Gills	Bronchial	Fish, crabs, tadpole larvae
Skin	Cutaneous	Earthworm, leech, amphibians
Trachea	Tracheal	Insects
