The Equilibrium Potential of K Ions in Nerve Cells Is

Multiple Choice

The equilibrium potential of K ions in nerve cells is about -90 mV.The membrane potential of typical nerve cells at rest is -70 mV.Therefore

A) Increasing the permeability of a resting neuronal membrane to K ions will increase the membrane potential (that is, make it more negative, inside with respect to outside)
B) In nerve cells at rest, there is a net diffusion of K ions out of the cell
C) Increasing the membrane potential of a nerve cell would slow the diffusion of K ions out of it
D) Potassium is not the only permeant ion at rest
E) All of the choices are true
