The first event is the capturing of light energy (color E orange) by pigments in the membrane Each photosystem II contains at least 99 cofactors: 35 chlorophyll a, 12 beta-carotene, two pheophytin, two plastoquinone, two heme, one bicarbonate, 20 lipids, the Mn 4 CaO 5 cluster (including two chloride ions), one non heme Fe 2+ and two putative Ca 2+ ions per monomer. There are several crystal structures of photosystem II. 1. there are two types, Photosystem I and Photosystem II 2. antenna complexes are highly organized arrangements of pigments, proteins, and other molecules that capture light energy 3. energy is transferred to a reaction center where electrons are actually moved into electron transport chains Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants.

Based on these results, a specific role for tocopherol in scavenging 1 O 2 * and protecting PS II from photoinhibition has been proposed (Krieger-Liszkay and Trebst, 2006). Several mutants of Chlamydomonas that affect PS II photodamage and repair have been identified by screening for enhanced susceptibility to photoinhibition at moderate PFDs (e.g.

3. Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis.It is located in the thylakoid membrane of plants, algae, and cyanobacteria.Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to Modern cells capture light using photosystem proteins, such as the one pictured here from PDB entry 1s5l . These photosystems use a collection of highly-colored molecules to capture light.
