The given diagram shows the scheme of:
| 1. | Cyclic photophosphorylation and Y is NADPH |
| 2. | Cyclic photophosphorylation and Y is ATP |
| 3. | Non-Cyclic photophosphorylation and Y is NADPH |
| 4. | Non-Cyclic photophosphorylation and Y is ATP |
The products of non-cyclic photophosphorylation include:
| 1. | ATP and P700 | 2. | ATP and NADPH |
| 3. | ADP and NADP | 4. | P700 and P680 |
The extra ATP required [as compared to NADPH] in Calvin cycle comes from:
| 1. | photosystem II | 2. | photosystem I |
| 3. | cyclic electron flow | 4. | non cyclic electron flow |
| I: | A possible location where this could be happening is in the stroma lamellae. |
| II: | While the membrane or lamellae of the grana have both PS I and PS II, the stroma lamellae membranes lack PS II as well as NADP reductase enzyme. |
| 1. | Only I | 2. | Only II |
| 3. | Both I and II | 4. | Neither I nor II |
