4. Origin of life
Let's consider the fourth
condition of realisation of model of charges
transfer: Thermodynamic reversibility
of charge transfer on SCIHB. Feature of the mechanism of charge
transfer on SCIHB is possibility of their
only unitary passage on system of bonds in one direction. However
this process can take place successful in the opposite direction. To it can
promote identity of donors (D1=D2) and acceptors (A1=A2),
participating in reception of charges in direct and return directions, and also
symmetry of donor and acceptor sites of SCIHB. Symmetry of SCIHB can be created
on the basis of the identical substructures laid symmetrically under the
relation to each other. At molecular level it is shown that the majority of biostructures consists of identical subunits, and their number,
as a rule, is even.
Whether it is possible on the
basis of requirement reversibility of
charge transfer to present an origin of live beings? It appears it is
possible, but for this purpose it is necessary to take into consideration one
more theory. It is considered, that the science has not given till now the
unequivocal answer to a question on a life origin. However, actually the answer
is found for a long time already, though has not received sufficient
popularity. It is a question of the theory evolutionary catalysis, developed by
prof. A.P. Rudenko [2]. In
a short form it is stated in the book [1].
Within the limits of the
evolutionary catalysis theory object of chemical
evolution in which course there were biosystems, is the elementary opened
catalytic system (EOCS), i.e. complete set of the catalyst, reacting substances
and products in all phases catalytic stages, connected in a uniform kinetic
continuum. Such objects which basis of existence is basic process,
have passed in process of long evolution and selection the way which has led to
occurrence of biosystems.
A.P. Rudenko's
theory describes the general laws of chemical evolution, not concretising the mechanism of carrying over of charges
which can underlie realization of basic reaction. However at transition
directly to an origin of biosystems it is necessary
to consider the concrete mechanism of carrying over of charges in them too.
As we saw, the
mechanism of charges transfer on SCIHB can be realised
only under condition of symmetric subunit organizations of structures. In book
[1] prebiological structures with such organization
are named EDOCS (elementary duplicated opened catalytic systems). Subunit
structure of EDOCS creates a condition for their interaction at population
level and exchange by subunits therefore structures with higher symmetry and
higher capacity of basic reaction can be formed. In turn, it increases duration
of their existence and possibility of participation in the subsequent
recombination. Such mechanism of recombination and selection of EDOCS on a
maximum of basic process carries the name of population-template model as
passes at level of the population which is simultaneously a template
of selection too.
