Consider the given two statements:
| Assertion (A): | It is possible to make calculations of the net gain of ATP for every glucose molecule oxidised; but in reality this can remain only a theoretical exercise. |
| Reason (R): | These calculations can be made only on certain assumptions that are not really valid in a living system. |
| 1. | Both (A) and (R) are True and (R) correctly explains the (A) |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of the (A) |
| 3. | (A) is True but (R) is False |
| 4. | (A) is False but (R) is True |
