Which of the following is an INCORRECT statement regarding the equilibrium potential?
A) It is a steady state in which opposing chemical and electrical flows are equal and there is no net movement of the ion.
B) The equilibrium potential for K+ in a typical neuron is −90 mV.
C) The equilibrium potential for Na+ in a typical neuron is +60 mV.
D) The resting potential of a neuron is approximately −70 mV.
E) The membrane is much more permeable to Na+ than to K+.

Question

Quizplus · Accepted Answer

The membrane is much more permeable to K+ than to Na+, especially at rest, which is why the resting potential of a neuron is closer to the equilibrium potential of K+ than that of Na+.
