Photosystem II is the photosystem that generates the two electrons that will eventually reduce NADP+ in ferredoxin-NADP-reductase. (goldenssport.com)
Dr Matt Johnson, reader in Biochemistry at the University of Sheffield and one of the supervisors of the study added: "Cytochrome b6f is the beating heart of photosynthesis which plays a … Afterward, the electron acceptor of PSI may redirect electrons to ferredoxin-thioredoxin reductase (FTR) to form reduced thioredoxin, to ferredoxin-NADPH reductase (FNR) to generate NADPH, or to molecular oxygen to form hydrogen peroxide (H2O2).

Type I photosystems use ferredoxin-like iron-sulfur cluster proteins as terminal electron acceptors, while type II photosystems ultimately shuttle electrons to a quinone terminal electron acceptor. (goldenssport.com)
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. (goldenssport.com)
Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH. (goldenssport.com)
The cytochrome b6f complex occupies a central position in the sequence of photosynthetic electron transport carriers, oxidizing plastoquinol (PQH 2) and providing the electron transfer connection between the two reaction center complexes, PS II and PS I, to which H + transfer is coupled, thus contributing to the trans-membrane.
