<span>Both photosystems have multi-protein complexes with pigments,
and an electron transport chain, in their thylakoid membranes reaction centers
that harvest energy from light photons and used for photosynthesis.

<span />
The difference
is that Photosystem II has a quinone-type reaction center <span>while that of photosystem I have
an iron-sulfur (Fe-S)-type. Additionally, in the electron chain reaction, photosystem
I pass the electron to ferredoxin, while Photosystem II contains plastoquinone,
which passes the energetic electron to cytochromes b6 and f.</span>
