Biological physics – rather recently appeared science. She is engaged in studying internal processes of all living organisms at all levels. One of key problems of this discipline is the research of the processes happening in sense organs.
On a joint of two disciplines studying fundamental laws of the nature there was such science as biophysics which main subject of study are regulation of the physical and physical and chemical processes happening in a human body, animals and plants. This discipline in the course of the development demanded for itself a number of subsections. There was it because studying an organism it has to is necessary to be carried out at various levels, only this way it is possible to understand regularities of its structure completely. The molecular biophysics researches the processes which are carried out in molecules and cells of sense organs. Very few people think of what difficult phenomena make work of a human body. Scientists deal with this problem, trying to understand, in particular, thanks to what actions the perception of taste, light and a smell is possible. Besides, its competence includes studying photosynthesis at plants. The processes happening in leaves which catch sunlight are of still huge interest and with its help process carbon dioxide into oxygen, thereby being one of the most important sources of air on Earth. The cellular biophysics is engaged in studying properties and rules of functioning of different cages – secretory, svetochuvstvenny, etc. Opening of electronic microscopes which allowed scientists to go deep in a cage research became a huge step forward. With their help, scientists revealed that practically all living organisms possess biochemiluminescence – ability to gleam. It happens because of intracellular oxidation of lipids on which intensity it is possible to consider the level of exchange reactions in an organism, and, as a result, to estimate its physical condition. Regulation and interrelation of bodies in an organism is studied by biophysics of management processes and regulation. Every second a huge number of various signals not only from the external environment, but also from internals comes to a brain. This subsection of biological physics is based on regularities which came to this science from cybernetics.
