Hints
| Assertion(A): | When glucose is catabolised to lactic acid, energy is liberated. |
| Reason(R): | In an exothermic reaction, the energy level of ‘Product’ (lactic acid) is lower than that of ‘Substrate’ (glucose). |
| 1. | Both (A) and (R) are true but (R) is not the correct explanation of (A) |
| 2. | Both (A) and (R) are true and (R) is the correct explanation of (A) |
