  1. 1. Characterization of auxiliary membrane proteins in the chloroplast of Arabidopsis thaliana

    University dissertation from Umeå : Umeå universitet

    Author : Lotta von Sydow; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis; chaperone; chloroplast; Cytochrome b559; FtsH; membrane proteins; photosynthesis; Photosystem II; protease; PsbY.; Arabidopsis; chaperone; Cytochrome b559; fotosyntes; fotosystem II; FtsH; kloroplast; membranprotein; proteas; PsbY.; biokemi; Biochemistry;

    Abstract : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. READ MORE

  2. 2. Oxidation and reduction reactions of the water-oxidizing complex in photosystem II

    University dissertation from Umeå : Umeå University

    Author : Long Vo Pham; Umeå universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosystem II PSII ; oxidation; reduction; flash induced oxygen evolution pattern FIOP ; water; oxygen; global fitting program GFP ; thylakoids; fysikalisk kemi; Physical Chemistry;

    Abstract : The oxygen that we breathe and food that we eat are products of the natural photosynthesis. Molecular oxygen is crucial for life on Earth owing to its role in the glycolysis and citric acid pathways that yield in aerobic organisms the energy-rich ATP molecules. READ MORE

  3. 3. The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature

    University dissertation from Biochemistry Department Lund University P.O. Box 124 SE-22100 Lund Sweden

    Author : Susan F Morvaridi; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Naturvetenskap; Temperature; Natural science; pH; EPR; S cycle; Photosystem II;

    Abstract : PSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. READ MORE

  4. 4. Electron Donor Systems in Natural and Artificial Photosynthesis

    University dissertation from Department of Biochemistry, Lund University

    Author : Ann Magnuson; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solar energy; artificial photosynthesis; Photosystem II; EPR; Biology; Biologi;

    Abstract : Photosynthesis is the process by which light energy is converted into chemical products, in photoautotrophic bacteria, algae and plants. The principal idea is the production of reducing agents by photo-induced oxidation of a sacrificial electron donor. READ MORE

  5. 5. Photosynthetic water oxidation the function of two extrinsic proteins

    University dissertation from Umeå : Fysiologisk botanik

    Author : Tatiana Shutova; Umeå universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. READ MORE
