Abstract
Effects of D2O substitution on electron transport reactions in proteins were analysed on the basis of generally adopted ideas of electronic vibration interactions and conformational mobility of macromolecules. At the molecular level, a mechanism for cytochrome c oxidation was established. On the basis of general viscosity and elasticity properties of proteins, the effects of temperature and chemical composition of the medium on conformational relaxation were analysed. For chromatophores of photosynthetising bacteria, a mechanism is discussed by which abnormal effects of temperature and abnormal isotope effects may be exercised on charge recombination.
