Answer:
Cyclic photophosphorylation just accomplishes the ADP to ATP process for immediate energy for these cells. This process uses only photosystem I and the chlorophyll P770000. It transports the cyclic electron. Electrons here travel in a cyclic manner and electrons travel back to photo system I and only ATP is produced. While non cyclic photophosphorylation uses both photosystem I and photosystem II acting in series. In this, it transports a non cyclic electron. The active reaction center in non cyclic photophosphorylation is P668800 and electrons travel in a non cyclic manner. The electrons from photo system I is accepted by NADPH. In this process both NADPH and ATP are produced. The process of photolysis or water splitting is present unlike cyclic photophosphorylation and towards the end oxygen is evolved as a byproduct. The system happens to be mostly predominant in green plants. Photosystem II is located in the inner surface of grana thylakoid membrane.
