WebThe pathway of electrons. The general features of a widely accepted mechanism for photoelectron transfer, in which two light reactions (light reaction I and light reaction II) occur during the transfer of electrons from water to carbon dioxide, were proposed by Robert Hill and Fay Bendall in 1960. This mechanism is based on the relative ... WebPhotosystem 2 (PS2) A light capturing protein complex in the thylakoid membrane of a chloroplast; splits water into electrons, protons, and oxygen gas. Electron Transport Chain moves high energy electrons from PS2 and PS1 and uses the lost energy from the electrons to pump hydrogen ions into the thylakoid lumen/space ATP Synthase
