Q. No.| I: | The water-splitting complex is located on the inner side of the thylakoid membrane |
| II: | The NADP reductase enzyme is located on the stromal side of the thylakoid membrane |
| 1. | Only I is correct |
| 2. | Only II is correct |
| 3. | Both I and II are correct |
| 4. | Both I and II are incorrect |
Immediately after light becomes unavailable, the biosynthetic phase of photosynthesis continues for some time and then stops. If then, light is made available, the synthesis starts again. A logical conclusion of these observations will include:
I. Biosynthetic phase does not directly depend on the presence of light.
II. Biosynthetic phase depends on the products of light reactions.
III. Biosynthesis phase occurs only in the dark or in the absence of light.
| 1. | Only I and II | 2. | Only III |
| 3. | Only II | 4. | I, II and III |
The light independent reactions are seen in:
I. carbon fixation
II. carbon fixation
III. Crassulacean acid metabolism
| 1. I and II only | 2. I and III only |
| 3. II and III only | 4. I, II and III |
In photosynthesis, the light-independent reactions take place at
| 1. thylakoid lumen | 2. photosystem l |
| 3. photosystem ll | 4. stromal matrix |
