The Nernst equation specifies the equilibrium potential for a particular ion.This equilibrium potential is a function of _____.
A)hydrostatic pressure
B)ion concentration gradient
C)osmotic gradient
D)temperature (thermal)gradient
E)the ion concentration gradient and the temperature (thermal)gradient

Question

Quizplus · Accepted Answer

The Nernst equation relates the equilibrium potential of an ion to its concentration gradient, as well as the charge on the ion and the temperature. It does not take into account hydrostatic pressure, osmotic gradient, or any other gradients besides the ion concentration gradient. Therefore, the best choice is B, which indicates that the equilibrium potential is a function of the ion concentration gradient.
