). From the thermodynamic viewpoint, mutual information constitutes the entropic contribution of the free energy that comes from the fuel. As mutual information is constant in the stationary state, changes in mutual information due to the chemical processes and mechanical processes are balanced . If, as in the above situation, İ > 0, the chemical transitions are producing mutual information that is consumed by the mechanical ones. Therefore, according to equation (3), the information flow accounts for the part of fueling free energy that contributes to increasing the system's mutual information during chemical transitions and which is subsequently erased by mechanical shuttling.
