AnnotationEducational film for university students. In biological systems, the set of functionally important processes is due to electron transfer reactions. In this connection, suffice it to mention, for example, respiration and photosynthesis. In terms of intermolecular electron transfer chemistry is nothing else than the redox reaction. electron transfer in proteins from the point of view of physics is one of the simplest processes functionally significant. In this example you can clearly trace how the transition from structurally unorganized chemical reactions, such as solutions to agreed successive stages inherent in biological systems. It is important that nature uses with no new interactions and organizes the process due to certain selection of molecular structures. However, there is still much to do before the physical mechanisms intraprotein processes become predictable and clear in every detail.
