Photosystem II provides the electrons necessary for the entire photosynthesis process by replacing lost electrons with electrons obtained from the splitting of water.

By oxidising water to produce hydrogen ions and molecular oxygen, the energetic electrons are swapped out for new ones. The photosystem II. Photosystem II provides the electrons necessary for the entire photosynthesis process by replacing lost electrons with electrons obtained from the splitting of water. The hydrogen ions (protons) produced when water is oxidised contribute to the formation of a proton gradient that ATP synthase uses to produce ATP.
