Organism as a biological system, adapted to the use of quantized energy of the electron transport by free radicals
The possibility of using by the organism of the quantized energy of the electron transport by free radicals was substantiated. It was shown that the liquid internal of organism of chordates from Amphioxus to mammals and man is the oxidant superoxide generating system, the basis of which is the blood, wherein heme is converted into hemin with the formation of superoxide. In experiments the model of blood in our experiments were coproporphyrin solutions (analogue of heme) activated by light quanta or metal-coordinator. The flow of the radical active species to the surface of cells in the area of fluids microcirculation is the factor of internal environment, to which the chordates biosystem has adapted. It is known that the organism of animals of different classes uses quantized energy of photons and electron transfer by free radicals. In the course of evolution under the internal and external oxidative impact the adaptations were developed to maintain the balance of oxidant and antioxidant systems and capacity variation of local streams of free radicals on cells of various organs. The flow of superoxide serves as a factor of the depolarization of the cell membrane, involves in the mechanism of excitation of myocardium fibers and nervous system cells, acting as a polarization modulator of cell surface and the trigger of potential action, as well as the potential governing the ion, including voltage-gated sodium channels of neurons membranes. The role of superoxide in the neurohumoral regulation of body functions has been exemplified by the differences in the structure of endothelial cells and the basement membrane capillaries, by the heart structure of mammalian and arrangement of brain neurons relative to capillaries. It was found that the morphological features of the structure of walls of capillaries in various organs provide selective flow of radicals from the liquid substance at the cellular surface, which allows to regulate the power of flow and quantized energy of electron transport. Single-electron transfer by free radicals is a source of electromagnetic phenomena in the dipole network of cell surfaces and automatic developments in the heart, brain and other organs of the biosystem.
