Consider the given two statements:
| Assertion (A): | Carbon dioxide is not produced in glycolysis. |
| Reason (R): | Glycolysis is a metabolic pathway that does not require oxygen. |
| 1. | (A) is True but (R) is False |
| 2. | Both (A) and (R) are True and (R) correctly explains (A) |
| 3. | Both (A) and (R) are True and but (R) does not correctly explain (R) |
| 4. | (A) is False but (R) is True |
| 1. | Conversion of Glucose into Glucose-6-phospahte |
| 2. | Conversion of Fructose-6-phosphate into Fructose 1,6-biphospahte |
| 3. | Conversion of 1,3 biphoshoglyceric acid into 3-phosphoglyceric acid |
| 4. | Conversion of Phosphoenol pyruvate into Pyruvic acid |
| Assertion (A): | In aerobic cellular respiration the presence of oxygen is vital. |
| Reason (R): | Oxygen acts as the final hydrogen acceptor. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | (A) is True but (R) is False |
| 3. | (A) is False but (R) is True |
| 4. | Both (A) and (R) are True but (R) does not correctly explain (A) |
| Assertion (A): | ATP is used at two steps in glycolysis. |
| Reason (R): | First ATP is used in converting glucose into glucose-6-phosphate and second ATP is used in conversion of fructose-6-phosphate into fructose-1-6-diphosphate. |
| 1. | (A) is False but (R) is True. |
| 2. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 3. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 4. | (A) is True but (R) is False. |
