Consider the given two statements:
| Assertion (A): | It is better to consider the respiratory pathway as an amphibolic pathway rather than only as a catabolic one. |
| Reason (R): | Breaking down processes within the living organism is catabolism, and synthesis is anabolism. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | Both (A) and (R) are True but (R) does not correctly explains (A) |
| 3. | (A) is True but (R) is False |
| 4. | (A) is False but (R) is True |

In glycolysis:
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
| I: | ATP is utilised at two steps: first in the conversion of glucose into glucose 6-phosphate and second in the conversion of fructose 6-phosphate to fructose 1, 6-bisphosphate. |
| II: | ATP is produced at two steps: first in the conversion of BPGA to 3-phosphoglyceric acid (PGA), and second during the conversion of PEP to pyruvic acid. |
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
