Temperature Effect on the Basis States for Charge Transfer Through a Polypeptide Fragments of Proteins and on the Nanocurrent in It

Abstract

To date, there exists already a wealth of information concerning the processes, which occur in the course of the donor-acceptor electron transfer between organelles of those cells, which are polypeptide fragments of protein molecules. Particularly, investigations were carried out in order to understand the influence of temperature upon these processes. However, the problems, which are connected with the charge transport mechanisms over the organelles, are in the stage of investigations yet. The influence of temperature upon such charge transport has not been investigated yet as well. The present article is devoted to investigation of this problem. Particularly, the following problem was investigated: correspondence of the model of electron transfer by polypeptide fragments of proteins, which was accepted for the previous investigations, for arbitrary temperature. The main check feature for such correspondence was accepted as follows: natural physical fact concerning the absence of current in the absence of external electrostatic of fields at any temperature. It was demonstrated that there exists very essential power-law dependence between the energetic position of each separate conduction band state and temperature. This dependence is determined by the factor 227°/T. However, in the aggregate all of these states ensure the absence of current in the conditions of the complete absence of violation of the electrostatic equilibrium of the system. That is, it was demonstrated that within the accepted model of conductance of the polypeptide fragment of protein, temperature actually has no influence upon occurrence of current from the injected electron provided that external electrostatic reasons for current occurrence are absent.
