  1. 16. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    Författare :Sindra Peterson Årsköld; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Sammanfattning : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). LÄS MER

  2. 17. NADH:quinone oxidoreductase: the black box of the respiratory chain

    Författare :Robert Roth; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NADH:quinone oxidoreductase; Complex I; electron transport; membrane protein; ubiquinone; respiratory chain; respiration; metabolism; Metabolism; Biokemi; Biochemistry;

    Sammanfattning : Complex I or NADH:quinone oxidoreductase the largest, most complex and least understood of the five membrane-bound enzyme complexes constituting the mitochondrial respiratory chain. The enzyme is present in all types of organisms, from bacteria to mammals. LÄS MER

  3. 18. Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis

    Författare :Joakim Högblom; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Hydrogen; EPR; Cobalt; Biokemi; metabolism; Biochemistry;

    Sammanfattning : The work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. LÄS MER

  4. 19. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis

    Författare :Gustavo Abreu-Vieira; Jan Nedergaard; Eric Ravussin; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

    Sammanfattning : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

  5. 20. Crisis in Energy Metabolism - Mitochondrial Defects and a New Disease Entity

    Författare :Gittan Kollberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Energy metabolism; Mitochondrial Disorders; mtDNA; multiple mtDNA deletions; Alpers-Huttenlocher syndrome; POLG1; GYS1; glycogen synthase; point mutation; Polymerase gamma;

    Sammanfattning : Impairment of energy metabolism may be associated with severe implications for affected individuals since all fundamental cell functions are energy-dependent. Disorders of energy metabolism are often genetic and associated with defects in the oxidative phosphorylation in mitochondria. LÄS MER
