Quizplus · Accepted Answer

The Nernst equation describes the relationship between the ion gradient across a membrane and the equilibrium potential for that specific ion when the membrane is permeable only to that ion. It calculates the voltage necessary to balance the concentration gradient of the ion, preventing net movement across the membrane.
