It catalyzes the light-induced reduction of plastoquinone by water through a number of redox reactions. The electron transport chain in PS II is composed of various protein-bound 2.

SUMMARY—LIGHT DEPENDENT REACTIONS a. Overall input light energy, H2O. b. Since P. tricornutum photosystem cores tend not to segregate as discrete bands along sucrose density gradients (Lepetit et al., 2007, 2010), thylakoid membranes were solubilized to a final concentration of 2% α-DDM (w/v) to improve separation of the photosynthetic membrane protein complexes. A noncyclic electron flow starts in photosystem 2. The electrons are transferred to photosystem 1 and then transferred to NADP+ in order to produce NADPH. 1.

Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. 2. Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced. 3. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen. 4. 2020-04-07 Each photosystem is made of two components: 1) antenna complex that consists of 300-400 chlorophyll a and b molecules and other accessory pigments such as carotenoids and 2) reaction center that consists of one or more chlorophyll molecules with a primary electron acceptor.

Introduction The major antenna complex of Photosystem II (PSII) is composed by the Lhcb1,2 and 3 gene products organised into heterotrimers. It has been shown that heterotrimeric LHCII complexes are connected to the PSII core in distinct positions thus building up a supramolecular complex in which the structural and functional role of individual Lhcb1-3 proteins is still to be elucidated 4 Feb 1999 Photosystem II is a multisubunit pigment−protein complex embedded in the thylakoid membranes of chloroplasts. It utilizes light for 13 Mar 2012 photosystems I and II, as active components for the light-induced generation of electrical power or fuel products. Nonetheless, no integrated Photosystem II (PSII) has a P680 reaction centre containing chlorophyll 'a' that uses light atom extracted from water by PSII, releasing oxygen as a by-product.

The electrons and hydrogen ions are used to power the creation of ATP, and ultimately carbohydrates, in later stages of photosynthesis. Photosystem II (of cyanobacteria and green plants) is composed of around 20 subunits (depending on the organism) as well as other accessory, light-harvesting proteins. 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 4CaO The products of photosynthesis and the elemental oxygen evolved sustain all higher life on Earth. All oxygen in the atmosphere is produced by the oxygen-evolving complex in PSII, a process that changed our planet from an anoxygenic to an oxygenic atmosphere 2.5 billion years ago.
