How do photosystems 1 and 2 differ?

There are two parts to both photosystems:

1. Reaction hub

-Transforms photon energy into kinetic energy of electrons by releasing four high-velocity electrons, which are then transported by the electron transport system (ETS) to NADP and ADP to produce the energy-rich molecules ATP and NADPH.

2. Antenna molecules, systems, or complexes for harvesting light:

As the name implies, the LHC gathers photons of light and modifies their wavelength to roughly 700 nm (PS I) or 680 nm (PS II), the wavelength at which the reaction center operates at its best.

While both photosystems are involved in the production of NADPH, Photosystem I primarily functions in cyclic electron flow, while Photosystem II primarily produces oxygen through non-cyclic electron flow and the splitting of water. These are the main differences between Photosystems I and II. Reaction Center Pigments: Photosystem I contains a chlorophyll a molecule with an absorption peak at 700 nm, while Photosystem II contains a chlorophyll a molecule with an absorption peak at 680 nm. 2. Electron Donor: In Photosystem I, the electron donor is plastocyanin; in Photosystem II, the electron donor is water. 3. Final Electron Acceptor: In Photosystem I, the final electron acceptor is NADP+, while in Photosystem II, the final electron acceptor is plastoquinone. 4. Function: Photosystem II primarily functions in non-cyclic electron flow and the production of oxygen. Overall, while both photosystems are involved in
