Nernst equation, action potentials

Thus, a 10 1 transmembrane gradient of a single monovalent ion, say potassium, will generate a membrane potential of 58 mV. See Resting Potential Action Potential Depolarization Threshold Potential Nernst Equation Goldman Equation Patch-Clamp Technique... 

The course of electron transfer reactions (redox reactions, see p. 14) also follows the law of mass action. For a single redox system (see p.32), the Nernst equation applies (top). The electron transfer potential of a redox system (i. e., its tendency to give off or take up electrons) is given by its redox potential E (in standard conditions, E° or E° ). The lower the...

The transmembrane potential at the peak of the action potential can be predicted from the Nernst equation by substituting appropriate sodium ion concentrations for those of potassium ions. 

In equilibrium systems, the law of mass action tells us that one can influence the tendency of the reaction to proceed by varying the concentrations of the reactants and products. Consequently, one can anticipate that the reduction potential for a given half-reaction will likewise vary with concentrations of the constituents. This relation is defined by the Nernst equation ...
