The influence of membrane potentials on reaction rates. Control in free-energy-transducing systems
Abstract:
The influence of membrane potentials on the rates of reactions involving the translocation of charged species across the membrane has been studied. Depending on the location of the rate-limiting step relative to the potential gradient either the forward or the backward rate is most strongly influenced by the potential. The rate of a proton translocation process in general is thus not a unique function of the protonmotive force. It is essential to include an explicit potential dependence in the kinetic coefficients to obtain a realistic description of the dynamics.

The Resting Membrane Potential
Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
