As powerful as diffusion is, cells sometimes must move materials in the opposite direction—against a concentration difference. This is accomplished by a process known as active transport. As its name implies, active transport requires energy.

The correct answer for this question is ion concentration gradient.
The membrane potential at which an ionic species is at equilibrium, that is, when there is no net movement of the ion across the membrane, is known as the Nernst potential for that specific ionic species. The equilibrium potential (Ve-.) for an ion is hence the Nernst potential for that ion.
Na+ and K+ have equilibrium potentials of +60 mV and -88 mV, respectively, in mammalian neurons. The Nernst equation, where R = gas constant, can be used to determine the reversal potential for a given ion.
The membrane potential that precisely balances the concentration gradient of an ion across the membrane is known as equilibrium potential.
