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 +
