Photosystem I and NADPH Formation

Photosystem I helps convert light energy into NADPH during photosynthesis. It works with photosystem II in the thylakoid membrane of the chloroplast, but it uses a different electron supplier and a different electron acceptor.

Electrons excited in photosystem II move to photosystem I through an e...

Similar to photosystem II, photosystem I also has the core domain called the P700 reaction center and a peripheral domain called the light harvesting complex.

The electrons are transferred from PSII to PSI through a series of electron acceptor molecules, starting from an electron carrier– plastoquinone, followed by a cytochrome complex, a...
