An ion's net electrochemical force will tend to move that ion across the membrane in a direction that will cause membrane potential to move toward that ion's equilibrium potential.

Question

Quizplus · Accepted Answer

The net electrochemical force acting on an ion across a membrane drives the ion in a direction that will help establish an equilibrium state, where the membrane potential approaches the ion's equilibrium potential. This is due to the combined effects of the chemical gradient (concentration difference) and the electrical gradient (voltage difference) acting on the ion.
