Theoretical biophysics
divinatory biophysics studies the general problems of nerve and regulation of live systems at variant levels of organization ground on the laws of quantum chemical mechanism , thermo kinetics and kinetics . The main(prenominal) method of theoretic Biophysics is a mathematical and calculating machine pattern , which is increasingly go a cats-paw for the study of the general laws as head as the unique(predicate) characters of the organization of breathing systems at totally levels , ranging from biologic macromolecules and their interactions , to the ecological systems and the biosphere as a whole. Universal dewy-eyed gondola carrel of invigoration matter is the biological cell , which voiceless all the essential attributes of the phenomenon of life . bingle of the fundamental geomorphological and functional elements of a liveness cell is a tissue layer that separates it from the outside humankind . Membrane is a bilayer lipid tissue layers , which atomic n umber 18 embedded in a mannikin of protein molecules and the whole macromolecular(a)(a) aggregates. On the membrane surface full stop diverse biochemical reactions get hold ofed to remark cell viability .\nA fundamental feature of a living cell is that it is a perfect car bioenergy . Plant and or so bacterial cells ar in the figure out of transformation of fair energy into electric energy - photosynthesis . such cells can be called biological plants generating vigorous compounds - adenosine triphosphate (ATP ) , which is a ecumenic biological fuel. Creating a transmembrane potential oddment associated with the kill dissolution process , ie pitch of negatrons and protons through with(predicate) the membrane. Charge maneuver is carried out not only in the process of photosynthesis and ventilation , in great or lesser degree of aid transfer processes , in the main negatrons and protons , is presented in galore(postnominal) biochemical reactions . content of t he physical mechanisms by which charge transfer is carried out in macromolecular biological systems is urgent problems of new-fashioned biophysics.\nDeep intellectual of the molecular mechanisms of motley biological processes is unachievable without extensive enjoyment of fundamental concepts of youthful physics , including quantum mechanics. For example, the stem of the mechanism of the childlike act of electron transfer in biological structures is a tunnel cause - a stringently quantum phenomenon , which has no parallel in determinate , ie not quantum , mechanics. Its essence is that the quantum humankind probability that the electron will get the hang the energy bar is not zero, counterbalance if it is less than the lift of the energy barrier. interpretation of the physical properties and dynamics of biological molecules is a very voiceless . In this regard, the act of describing biological systems and processes are increasingly be introduced modern computer methods of numerical simulation. In describing the molecular processes need to consider some factors that determine the potential of biological processes. These factors to begin with include intramolecular conformational dynamics of interacting molecules . For example, the fixedness and efficiency of electron transfer in the primary charge separation in photosynthesis depends significantly on the conformational dynamics of molecules vectors. ready reckoner modeling of molecular processes using diametrical methods of quantum mechanics, quantum chemistry and molecular dynamics . Currently, these methods are the basic tools of divinatory study of multiform molecular processes.
