Answer 1

The upcoming discussion will update you about the differences between PS I (photosystem I) and PS II (photosystem II).

PS I:

1. It is Pigment system I or Photosystem I.

2. Located in non-appressed part of granna thylakoids as well as stroma thylakoids.

3. Reaction centre is P700.

4. Chlorophyll: Carotenoids is 30: 1.

5. Chlorophyll a content is more than chlorophyll b.

6. It performs cyclic photophosphorylation independently.

PS II:

1. It is Pigment system II or Photosystem II.

2. Present in appressed part of granna thylakoids.

3. Reaction centre or photocentre is P680.

4. Chlorophyll: Carotenoids is 7: 1.

5. Chlorophyll b is more than chlorophyll a.

6. It performs non-cyclic photophos-phoiylation in combination with PS I.
