| Statement I: | RuBisCO is the most abundant enzyme in the world. |
| Statement II: | Photorespiration does not occur in C4 plants. |
| 1. | Statement I is correct but Statement II is incorrect |
| 2. | Statement I is incorrect but Statement II is correct |
| 3. | Both Statement I and Statement II are correct |
| 4. | Both Statement I and Statement II are incorrect |
The oxygenation activity of RuBisCo enzyme in photorespiration leads to the formation of:
| 1. | 1 molecule of the 3-C compound |
| 2. | 1 molecule of the 6-C compound |
| 3. | 1 molecule of a 4-C compound and 1 molecule of the 2-C compound |
| 4. | 2 molecules of the 3-C compound |
The process which makes a major difference between C3 and C4 plants is:
| 1. | glycolysis | 2. | Calvin cycle |
| 3. | photorespiration | 4. | respiration |
