Equilibrium potential for an ion is calculated using:: (A) Gibbs-Donnan equation, (B) Nerst equation, (C) Goldman equation, (D) None
Answer is B. B i.e. Nernst equation Equilibrium potential (i.e., membrane potential at which equilibrium b/w concentration & electrical gradient exist) for any (one) univalent ion is calculated by Nernst equationQ and for several different ions by Goldmann- Hodgkin-katz equation.
