उत्तर
| Respiration | Combustion | |
| 1. | It takes place within live cells. | The process is noncellular. |
| 2. | The process of respiration is biochemical. | The process of combustion is physio-chemical. |
| 3. | The majority of energy is held within ATP molecules. | No ATP is produced. |
| 4. | At the conclusion of the process (terminal oxidation) between reduced coenzymes and oxygen, oxidation takes place. | During combustion, the substrate is directly oxidised. |
| 5. | Step-by-step breaking of chemical bonds releases energy. | Due to the simultaneous occurrence of all chemical processes, energy is released in a single step. |
| 6. | Many intermediates are created. They are employed in the production of several organic chemicals. | In combustion, no intermediates are formed. |
| 7. | Enzymes are needed in large quantities, one for every stage or reaction. | The process of burning is not enzymatic. |
| 8. | Heat energy makes up less than 50% of the released energy. Seldom is light produced. | Light and heat energy are two forms of released energy. |
| 9. | Temperature is not allowed to rise. | Temperature becomes very high. |
