Knowing the ion concentrations on both sides of the plasma membrane makes it possible to calculate the membrane potential (Vm),because at equilibrium

Question

Quizplus · Accepted Answer

The equilibrium membrane potential is determined when the net flow of ions across the membrane is zero, which corresponds to a state where the Gibbs free energy change (ΔG) for ion movement is zero. This is because at equilibrium, there is no net energy change for moving ions across the membrane, allowing for the calculation of the membrane potential (Vm) based on ion concentrations.
