ADVERTISEMENTS:
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.
ADVERTISEMENTS:
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:
ADVERTISEMENTS:
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.
