Differences between Photosystem I and Photosystem II

Photosystem I

Photosystem II

1. The system is located in the nonappressed part of grana thylakoids as well as stroma thylakoids.

2. Chlorophyll: carotenoid content is high.

3. Chlorophyll a content is more than twice that of chlorophyll b.

4. Its photocentre is P700.

5. It receives electrons from photosystem II.

6. Photosystem I can perform cyclic photophosphorylation independently.

7. It is not connected with photolysis of water.

8. Usually it hands over its electron to NADP+.

1. Photosystem II is present in the appressed part of grana thylakoids.

2. Chlorophyll to carotenoid ratio is low.

3. Chlorophyll a and chlorophyll b are approximately equal.

4. Its photocentre is P680.

5. Electrons are received from photolytic reaction.

6. It performs non-cyclic photophosphorylation in conjunction with photosystem I.

7. Photosystem II is connected with photolytic oxidation of water.

8. Usually it hands over its electrons to PS I.
