In these light reactions, water is split (photolysis) to satisfy the electron debt in the chlorophyll molecules in the reaction center of photosystem II. The actual step that converts light energy into chemical energy takes place in a multiprotein complex called a photosystem, two types of which are found embedded in the thylakoid membrane, photosystem II (PSII) and photosystem I (PSI) (). This process is referred to as non- cyclic photophosphorylation because the lost electrons by P680 of . The general formula is: The Photosystem II does the first part of the reaction by splitting up water and transferring electrons to plastoquinone and also by generating H+ ions.
