Many different methods have been developed in recent years to gain insight into the structure of proteins, membranes, organelles and cells. Here we demonstrate the application of near-field scanning optical microscopy (NSOM) for analysis of the structures of typical photosynthetic membrane objects such as chloroplasts and thylakoids from spinach and chromatophores from purple bacteria. To our knowledge,...
Photosystem II (PS II) of plants and cyanobacteria, which catalyzes the light-induced splitting of water and the release of oxygen, is the primary source of oxygen in the earth atmosphere. When activated by short light flashes, oxygen release in PS II occurs periodically with maxima after the third and the seventh flashes. Many other processes, including chlorophyll (Chl) t a fluorescence, are also...
