Microtubules in eucaryotic cells form electrically polar structures, which satisfy conditions for excitation, energy condensation, and generation of endogenous electromagnetic field with strong electric near zone component. Large energy supply connected with continuous rebuilding of the microtubular structure and very likely with activity of motor proteins, and interfacial slip layer at the microtubule surface protecting vibrations in microtubules from viscous damping of the cytosol are important conditions for excitation and formation of coherent state. Generated electric field can exert a driving force for directed transport. The Wiener-Lévy process with symmetry breaking is used to describe motion of molecules and charges. Motion of molecules with diameter 1 and 5 nm at distances up to 50 nm is analysed. Transport driven by the electric field with inseparable thermal component has greater probability to reach the target than transport by thermal motion itself. Transport of electrons display similar dependence. Probability of any action depending on the ratio of the random and of the deterministic component of motion should be high enough to provide small number of errors but sufficiently low to comply with requirements for evolutionary changes.
