The upcoming discussion will update you about the difference between respiration and combustion.
Difference # Respiration:
1. This is a vital process; occurs inside living cells.
2. This is biochemical process.
3. Energy is released step by step.
4. Less than 50 per cent energy is liberated as heat.
5. There is very small rise in temperature.
6. Most of the energy is stored in ATP molecules.
7. Respiratory reactions are regulated by enzymes.
8. Several intermediates are formed.
9. Oxidation lakes place at the end of reaction between reduced coenzymes and oxygen.
Difference # Combustion:
1. This is a chemical process; does not require living cells.
2. This is physico-chemical process.
3. All the energy is released suddenly.
4. Most of energy is liberated as heat.
5. There is large increase in temperature.
6. ATP is not formed.
7. This is a non-enzymatic process.
8. In the process of combustion, no such intermediates are produced.
9. Substrate directly oxidises.
