Question

List out the differences between respiration and combustion.

Answer 1

Respiration

1. It takes place in living cells only.
2.It is a biological process.
3.It takes place at normal temperature.
4. It is carried out with the help of various enzymes.
5.Respiration is a slow process.Thus the energy is also liberated in several steps and remain stored in the form of ATP.
6.Only part of energy is liberated as heat.

Combustion

1. It does not take place in the living cell.
2.It is a chemical process.
3.It takes place at high temperature.
4.Enzymes are not involved in this process.
5.Combustion is a fast process in which the energy is liberated only in one step resulting in increase in temperature and production of fire.
6.Most of the energy is produced as heat.
