HI mate GM here is your answer.....,

Photosystem II contains chlorophyll a, as well as up to 50% chlorophyll b. It probably evolved later as a supplement to Photo I. It is needed to capture enough energy to do the biosynthetic reactions of the dark reaction. Its reaction center is a molecule called P680 which absorbs light maximally at 680 nm.

I hope it will help you and mark me as a brain list answer plz.

Answer:

Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. ... The combined action of the entire photosynthetic electron transport chain also produces a proton-motive force that is used to generate ATP.
