What happens when a photon of light hits photosyestem ll?

When a photon of light hits photosystem II, it excites an electron in the reaction center of the photosystem. This electron is then passed along a series of proteins in the electron transport chain, creating a flow of electrons that drives ATP production through chemiOSmosis. Additionally, the photon splitting water molecules into oxygen, protons, and electrons, which is essential for the plant to produce oxygen and obtain electrons to replace the excited ones.
