  6. 4. Energy and Electron Transfer in Porphyrin-Based Donor--Bridge--Acceptor Systems

    Author : Kristine Kilså; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron transfer; electronic coupling; donor--bridge--acceptor systems; quantum mechanical calculations; enhanced intersystem crossing; ligand and solvent effects; bridge mediation; energy transfer; porphyrin;

    Abstract : The photophysical properties of supramolecular donor--bridge--acceptor systems have been investigated by spectroscopic and quantum mechanical methods. The systems consist of porphyrin donor and acceptor moieties linked by bridging chromophores of varying excitation energy, and are shown to be geometrically well-defined in terms of length and rotational conformation.

  7. 5. Choreography of a proton pump : Studies of charge-transfer reactions in cytochrome c oxidase

    Author : Jóhanna Vilhjálmsdóttir; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; respiration; proton pump; electron transfer; proton transfer; proton-transfer pathway; midpoint potential; proton-pumping mechanism; Biochemistry; biokemi;

    Abstract : In the last step of cellular respiration, electrons from metabolites are transferred to molecular oxygen, mediated by the enzyme complexes of the respiratory chain. Some of these enzyme complexes couple these redox reactions to formation of an electrochemical proton gradient across the cell membrane. The proton gradient is used e.g. READ MORE
