Which of the following does not stem from the application of Ohm's law to ionic conductances?




  1. The driving force on the ionic current is the difference between the membrane potential and the ion's Nernst potential.
  2. The conductance for an ion is inversely proportional to the resistance of the membrane to the passage of that ion.
  3. All permeant ions experience an identical driving force at each time point during the course of an action potential.
  4. The conductance for each ion can be calculated based on the measured ionic currents and the calculated driving force.
  5. The calculations stemming from Ohm's law can be used to derive a mathematical description of the action potential.
