  3. 2. Regulation of electron donation to photosystem 1

    Författare :Daniel Farkas; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPR; NMR; photosystem 1; plastocyanin; protein-protein interaction; PsaF;

    Sammanfattning : Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions where water molecules are the source of electrons and NADP+ is the terminal electron acceptor. LÄS MER

    Sammanfattning : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.
