e Nernst Equation describes the relationship between the concentration difference of meating ion across a membrane and the membrane potential at equilibrium. The general form he equation is Ex = (RT / zF) × In ([X]out / [X]in), where Ex = membrane potential for ion x, R as constant, T = absolute temperature, z = valence of ion, F= Faraday's constant (charge per 1 ions), [X]out ion concentration outside, and [X]in = ion concentration inside. At room perature (18° C), and converting from natural logarithms (ln) to common logarithms (log), Nernst equation reduces to Ex = (0.058/z) × log ([X]out/ [X]in). What would the equilibrium entials be for each of the following ions at the given concentrations? NT: Use 58 in the Goldman equation for results in mV or 0.058 for results in V. (A) [K*]out = 3 mM, [K*]in = 150 mM (B) [Na Jout = 100 mM, [Na]in = 10 mM (C) [Cl]out = 110 mM, [CI]in = 4 mM
