उत्तर
| Aerobic Respiration | Anaerobic respiration | |
| 1. | It occurs in the presence of oxygen. | It occurs in the absence of oxygen. |
| 2. | It occurs in three steps: glycolysis, the TCA (Krebs) cycle, and the electron transport chain. | It occurs in two steps: glycolysis and fermentation. |
| 3. | The end products are CO2, H2O, and energy. | The end products are organic acids, alcohol, and energy. |
| 4. | A larger amount of energy is generated. | A lesser amount of energy is generated. |
| 5. | Complete oxidation of glucose takes place. | Incomplete oxidation of glucose takes place. |
| 6. | It takes place in higher plants, animals, and certain aerobic microbes. | It takes place in yeast, muscle cells, erythrocytes, and some anaerobic microbes. |
