प्रश्न
Distinguish between Glycolysis and TCA cycle.
उत्तर
| Glycolysis | TCA cycle/Krebs cycle |
| 1. The process of glycolysis occurs in the cytoplasm of the cell. | 1. Krebs cycle takes place in mitochondria. |
| 2. In glycolysis, one molecule of glucose is oxidized step-by-step to produce two molecules each of pyruvic acid, ATP, NADH2, and water. | 2. In Krebs cycle, a molecule of acetyl-co-A is completely oxidized and in the process CO2, H2O, NADH2, FADH2, and ATP is produced. |
| 3. Glycolysis can take place in both aerobic and anaerobic respiration. | 3. Krebs cycle takes place only during aerobic respiration. |
| 4. The first step in cellular respiration is glycolysis where glucese is converted into pyruvate. | 4. The second step in cellular respiration is Krebs cycle. |
| 5. Two molecules of pyruvate are obtained in glycolysis. | 5. Pyruvate is converted into CO2 and H2O during Krebs cycle. |
| 6. Two molecules of ATP are used up in glycolysis. | 6. ATP molecules are not used up in Krebs cycle. |
| 7. Four molecules of ATP are produced in glycolysis. | 7. Two molecules of ATP are produced in Krebs cycle. |
| 8. CO2 is not produced during glycolysis. | 8. CO2 is produced in Krebs cycle. |
