Table 1 shows features of cyclic and non-cyclic photophosphorylation. Some entries are missing. Outline the missing information by writing the correct term(s) for (a) to (g).
| Feature | Cyclic photophosphorylation | Non-cyclic photophosphorylation |
|---|---|---|
| Photosystem(s) involved | PSI only | (a) |
| Electron flow path | (b) | Linear (from PSII to PSI) |
| Products | (c) | ATP, reduced NADP, and O2 |
| Source of electrons | (d) | Water (photolysis) |
| Role of oxygen-evolving complex | Not involved | (e) |
| Final electron acceptor | PSI (returns to PSI) | (f) |
| Primary function in Calvin cycle | Supplies (g) | Supplies ATP and reduced NADP |
