The equilibrium potential measures the point at which the force of the electrical gradient exactly opposes the force of the _______ gradient on a particular ion, thus preventing any net movement across the membrane.
A) concentration gradient
B) pressure gradient
C) osmotic gradient
D) thermal gradient

Question

Quizplus · Accepted Answer

The equilibrium potential is based on the concentration gradient of a particular ion. It is the point at which the electrical gradient exactly balances the concentration gradient, preventing any net movement of the ion across the membrane. Pressure, osmotic, and thermal gradients are not directly involved in the determination of the equilibrium potential.
