9. Give comparison between the following:
(b) Cyclic and non-cyclic photophosphorylation
Cyclic photophosphorylation | Non-cyclic photophosphorylation |
Only photosystem I is involved in cyclic photophosphorylation | Both photosystems I and II are involved in non-cyclic photophosphorylation |
The active reaction centre is P700 | The active reaction centre is P680 |
Electron transportation occurs in a cyclic manner | Electron transport occurs in a non-cyclic manner |
Oxygen evolution does not occur | Oxygen is released as a by-product |
Only ATP is produced | Both ATP and NADPH are produced |
