Assertion (A): | The respiratory process has traditionally been considered a catabolic process. |
Reason (R): | Respiration involves the breakdown of substrates. |
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. |
1. | NAD+ | 2. | oxygen |
3. | pyruvate | 4. | water |
1. | 2 | 2. | 3 |
3. | 4 | 4. | 6 |
I: | BPGA to 3-phosphoglyceric acid (PGA) |
II: | PEP to pyruvic acid |
Assertion (A): | It is better to consider the respiratory pathway as an amphibolic pathway rather than as a catabolic one. |
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. | Both (A) and (R) are False. |

3. | 1, 3 – BPG | 4. | 2 – PG |
Statement I: | In aerobic cellular respiration, the complete oxidation of pyruvate takes place in the cytoplasm. |

1. | (A) is True but (R) is False |
2. | Both (A) and (R) are True and (R) correctly explains (A) |
3. | Both (A) and (R) are True and but (R) does not correctly explain (R) |
4. | (A) is False but (R) is True |
