Fats and proteins can also provide us energy. For this to happen:
| 1. | Fats and proteins must first be converted to glucose |
| 2. | Fats and proteins must enter separate catabolic pathways of their own |
| 3. | Fats and proteins must be modified to forms that can enter the glucose metabolic pathway |
| 4. | Fats must first be converted to proteins that can enter the glucose metabolic pathway |
| Statement I: | Fatty acids would be broken down to acetyl CoA before entering the respiratory pathway when it is used as a substrate. |
| Statement II: | When the organism needs to synthesise fatty acids, acetyl CoA would be withdrawn from the respiratory pathway for it. |
| 1. | Statement I is correct; Statement II is incorrect |
| 2. | Statement I is incorrect; Statement II is correct |
| 3. | Statement I is incorrect; Statement II is incorrect |
| 4. | Statement I is correct; Statement II is correct |

| Assertion (A): | The respiratory pathway is an amphibolic pathway. |
| Reason (R): | The respiratory pathway is involved in both anabolism and catabolism. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
