Two main topics are addressed in this chapter:’ static heterogeneities’ of PS II, as they appear in standard dark-adapted material, and ‘dynamic heterogeneities’ possibly involved in the non-photochemical quenching processes that modulate the steady-state yield of PS II.

Inactive photosystem II centers: A resolution of discrepencies in photosystem II quantitation
Photosynthesis Research, 1990The abundance of photosystem II in chloroplast thylakoid membranes has been a contentious issue because different techniques give quite different estimates of photosystem II titer. This discrepancy led in turn to disagreements regarding the stoichiometry of photosystem II to photosystem I in these membranes.

Copper in photosystem II: association with LHC II
Photosynthesis Research, 1987Photosystem II particles from spinach and barley contained 2.5 and 4.2 Cu per 300 chlorophylls respectively. This Cu was resistant to removal by EDTA. A large percentage of the PSII Cu in both plants is associated with the light-harvesting chlorophyll a/b protein, LHCII; 46% in barley and 76% in spinach.

Organization of Plant Photosystem II and Photosystem I Supercomplexes
2018In nature, plants are continuously exposed to varying environmental conditions. They have developed a wide range of adaptive mechanisms, which ensure their survival and maintenance of stable photosynthetic performance. Photosynthesis is delicately regulated at the level of the thylakoid membrane of chloroplasts and the regulatory mechanisms include a ...

Electron transfer in photosystem II
Photosynthesis Research, 1985The picture presently emerging from studies on the mechanism of photosystem II electron transport is discussed. The reactions involved in excitation trapping, charge separation and stabilization of the charge pair in the reaction center, followed by the reactions with the substrates, plastoquinone reduction and water oxidation, are described ...

Photosystem II Based Multilayers
2017During billions of years of evolution and development, photosynthesis has formed an effective mechanism for solar energy fixation and conversion. The unique property of photosystem II (PSII) to split water in ambient condition makes it the key role in the process of photosynthesis.

Photosystem II (PS II) is a pigment-protein complex located in the chloroplast thylakoid membrane of plants and algae which acts as a light-driven water-splitting enzyme. At least 16 chloroplast- and 11 nucleus-encoded polypeptide subunits, several types of pigments, and lipid, metal and ion cofactors have been identified as constituents of the ...
