Photosystem- I is located in the non-appressed part of grana thylakoids as well as stroma thylakoids- In this photosystem- chlorophyll carotenoid content is high- Its photocentre is P700- Pigment molecules of PS- I absorb at or below 700nm wavelength of light- It receives electrons from photosystem- II- Photosystem- I is involved in both cyclic and non-cyclic photophosphorylation- It is not connected with photolysis of water- Usually- it hands over its electron to NADP-
