  1. 1. Photosystem II : organization, function and regulation

    Författare :Said Eshaghi; Matthias Rögner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : What makes plants, green algae and cyanobacteria so remarkable is their ability to convert light energy to chemical energy and at the same time evolve oxygen. In order to do so, they have developed a complex molecular machinery involving pigment and co-factor binding multi-protein complexes. LÄS MER

  3. 2. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxygenic Photosynthesis; Photosystem II; TR-MIMS; isotope exchange; EPR; EDNMR; water splitting; water oxidation;

    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.

  5. 4. Functions of REP27 and the low molecular weight proteins PsbX and PsbW in repair and assembly of photosystem II

    Författare :Jose Gines Garcia Cerdan; Wolfgang Schröder; Eva-Mari Aro; Umeå universitet; []
    Nyckelord :Photosynthesis; photosystem II reaction center; PSII-LHCII supercomplex; antisense plant; T-DNA knockout plant; auxiliary protein; Biochemistry; biokemi;

    Sammanfattning :     Oxygenic photosynthesis is the major producer of both oxygen and organic compounds on earth and takes place in plants, green algae and cyanobacteria. The thylakoid membranes are the site of the photosynthetic light reactions that involve the concerted action of four major protein complexes known as photosystem II (PSII), cytochrome b6f complex, ATP synthase and photosystem I (PSI).

  7. 5. The Far-Red Limit of Photosynthesis

    Författare :Fredrik Mokvist; Stenbjörn Styring; Tomáš Polívka; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Far-red light; Photosystem I; Photosystem II; P700; P680; EPR; Charge Separation; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Sammanfattning : The photosynthetic process has the unique ability to capture energy from sunlight and accumulate that energy in sugars and starch. This thesis deals with the light driven part of photosynthesis. LÄS MER
