The thermodynamic models available in the literature predict that during self-organizing processes the entropy of a cell considered as an open thermodynamic system
decreases. This prediction leads to conclusion that cell imports a certain amount of
negative entropy and generates entropy during irreversible metabolic processes.
The controversial concept of negentropy was criticized recently. In this research a
new model was proposed that is not based on the steady-state approximation and
describes living systems more realistically. The analysis of the suggested model of
an open thermodynamic system far from equilibrium, led to the conclusion that the
entropy during self-organizing processes increases during growth (of a molecule or
a cell). Using as models the synthesis of an oligopeptide and a growing hydrocarbon chain, it was shown that entropy of an open thermodynamic system increases
during addition of monomers (a self-organizing process). A derived equation confirms the re...sults obtained by calculations with literature experimental values of molar entropy. The decrease of entropy observed in self-organizing processes occurred only during phase transition.
