ADVERTISEMENTS:
The upcoming discussion will update you about the differences between Respiration and Combustion.
Difference # Respiration:
1. It occurs inside living cells.
2. It is under biological control.
ADVERTISEMENTS:
3. Respiration is a biochemical process.
4. Energy is released in stages as chemical bonds are broken in steps.
5. Less than 50% energy is liberated as heat.
6. Light is liberated in a very few cases.
ADVERTISEMENTS:
7. Temperature is not allowed to rise.
ADVERTISEMENTS:
8. Most – of the energy is trapped in ATP molecules.
9. Oxidation occurs at the end of reaction (terminal oxidation) between reduced coenzymes and oxygen.
10. A number of intermediates are formed. They are used in the synthesis of different organic compounds.
11. A number of enzymes are required, one for each step or reaction.
Difference # Combustion:
1. It is a non-cellular process.
2. Combustion is an uncontrolled process.
3. Combustion is a physicochemical process.
ADVERTISEMENTS:
4. Energy is released in a single step as all chemical steps occur simultaneously.
5. Most of the energy is liberated as heat.
6. Light is produced during combustion.
7. Temperature becomes very high.
ADVERTISEMENTS:
8. ATP is not formed.
9. The substrate is directly oxidized in combustion.
10. No intermediates are produced in combustion.
11. Burning is a non-enzymatic process.
