  1. 1. Protonmotive coupling of energy conversion processes in photosyntetic bacteria : studies on membrane energization and photophosphorylation capacity

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Beston F. Nore; [1990]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fotosyntes;

    Sammanfattning : This work is a study on the membrane-bound inorganic pyrophosphatase and other energylinkedenzymes in the chromatophores from the photosynthetic bacterium Rhodospirillum rubrum.The membrane-bound inorganic pyrophosphatase is functionally similar to the well-known FiF0-ATP synthase.

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Lotta von Sydow; Umeå universitet.; [2016]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Teaching photosynthesis in a compulsory school context Students' reasoning, understanding and interactions

    Detta är en avhandling från Umeå : Umeå universitet, Institutionen för naturvetenskapernas och matematikens didaktik

    Författare :Helena Näs; Umeå universitet.; [2010]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; teaching; primary and secondary school; plants; photosynthesis and respiration; Undervisning; mellan- och högstadiet; växter; fotosyntes och cellandning; SOCIAL SCIENCES Social sciences Education Subject didactics; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik Ämnesdidaktik; didactics of natural science; naturvetenskapens didaktik;

    Sammanfattning : According to previous research, students show difficulties in understanding photosynthesis and respiration, and basic ecological concepts like energy flow in ecosystems. There are successful teaching units accomplished in this area and many of them can be described as inquiry-based teaching. LÄS MER

  5. 5. Role of phagotrophy in freshwater phytoplankton

    Detta är en avhandling från Carina Pålsson, Limnology, Ecology Building, S-223 62, Lund, Sweden

    Författare :Carina Pålsson; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aquatic ecology; marine biology; limnology; mixotrophy; phagotrophy; phytoplankton; oligotrophic; clear-water lakes; grazing; competition; nutrient enrichment; autotrophy; heterotrophy; bacterial ingestion; Hydrobiology; Marinbiologi; akvatisk ekologi; limnologi;

    Sammanfattning : Some phytoplankton have the ability to combine phototrophy and heterotrophy within the same individual, which is called mixotrophy. In this thesis, I adress mixotrophy and competitive interactions of mixotrophs and obligate auto- or heterotrophs in relation to the availability of nutrients, light and prey. LÄS MER
