Which of the following statements is incorrect?
| 1. | Glucose is the favoured substrate for respiration |
| 2. | All carbohydrates are usually first converted into glucose before they are used for respiration |
| 3. | Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step |
| 4. | Fats directly enter the respiratory pathway |
The individual amino acid enter the respiratory pathway at
| 1. | Within Krebs’ cycle |
| 2. | As Pyruvate or Acetyl CoA |
| 3. | As PGAL |
| 4. | Both A and B |
For the synthesis of Fatty acids, which of the following substrates will be used?
| 1. | Acetyl CoA | 2. | PGAL |
| 3. | BPGA | 4. | Pyruvic Acid |
| Statement - I : | Respiration is amphibolic pathway. |
| Statement - II : | Pure fat & pure protein can never be respiratory substrate. |
Option :
| 1. | Only Statement - II is correct. |
| 2. | Both Statements are correct. |
| 3. | Neither first nor second is correct. |
| 4. | Only first Statement is correct. |

2. Pyruvic acid
3. Acetyl CoA
4. Glucose- 6 -phosphate
