Quizplus · Accepted Answer

The Goldman-Hokgkin-Katz equation takes into account the relative permeabilities and gradients for all permeable ions, allowing for the direct measurement of membrane potential. The Nernst equation only calculates the equilibrium potential for a single ion, and Fick's equation relates to the diffusion of molecules across membranes, not membrane potential.
