The Biophysical Modelling of the Criteria in the Living Systems

Abstract

Generally, the excitation is correlated with a local modification of the membrane potential; but if the depolarization is intense, it „propagates” and the electric features of the membrane of the entire cell change. The adaptation concept can have a narrower sphere, including only the functional, biophysical and anatomical modifications; in a wider meaning, the sphere extends to everything that represents changed functions and structures, which allow the development of life, even in extremely unfavourable environment conditions, until non lethal pathological alterations. Sexuality does not have only a reproductive biological function, but it has others as well: multiplicative, fortifying, selective, diversifying. The adaptation of organism to the life conditions is realized mainly by the adaptation of metabolism. Knowing the biophysical and biochemical regulation leads amongst others – to an even wider conception about the functions of the metabolism in the living organism.
