Abstract
The states of the charge transfer chain fragment depending on the charge localization are modelled by interaction with the two-level system as a source of dichotomous noise whose features depend themselves on the fragment states. Basing on the exact solution of the stochastic problem, we describe the noise-induced phase transitions of the (mono-bi)stability type which are possible even in the simplest case of the fragment represented by an overdamped harmonic oscillator. The results are discussed in the context of the functional nonlinearities in biological charge transport processes.
