The Equilibrium Potential is a Function of Which of the Following

Question

The equilibrium potential is a function of which of the following?
A)hydrostatic pressure
B)ion concentration gradients
C)osmotic gradient
D)temperature (thermal)gradient
E)protein gradients

Accepted Answer

The equilibrium potential is determined by the concentration gradient of the ion in question. It is the point at which there is no net movement of ions across a membrane due to the balance between the electrochemical force driving them across the membrane and the opposing force due to the concentration gradient. Therefore, ion concentration gradients are the most important factor in determining the equilibrium potential. The other options listed do not have a direct effect on the equilibrium potential.
