After electrons leave photosystem ii, they go into an electron transport chain of three protein complexes. where do they go after that electron transport chain?

The right answer is photosystem I

And the three protein complexes are : plastoquinone, cytochrome b6f complex, plastocyanin.

In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:

H2O ==> photosystem II (which contains P680) ==> plastoquinone ==> cytochrome b6f complex ==> plastocyanin → photosystem I (which contains P700) ==> ferredoxin ==> ferredoxin-NADP + reductase ==> NADP +
