Ionic driving force
WebIonic Driving Force: An ionic driving force is defined as the net force acting on an ion. It is equal to the difference of the membrane potential and the equilibrium potential of the ion. It describes how far the ion is from electrochemical equilibrium, that is equal amounts of ions inside and outside the cell. Answer and Explanation: 1 WebA. The driving force on the ionic current is the difference between the membrane potential and the ion’s Nernst potential. B. The conductance for an ion is inversely proportional to the resistance of the membrane to the passage of that ion. C. All permeant ions. Which of the following does NOT stem from the application of Ohm’s law to ionic ...
