ADVERTISEMENTS:
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.
ADVERTISEMENTS:
3. Energy is released step by step.
4. Less than 50 per cent energy is liberated as heat.
ADVERTISEMENTS:
5. There is very small rise in temperature.
6. Most of the energy is stored in ATP molecules.
ADVERTISEMENTS:
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.
ADVERTISEMENTS:
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.
