If the potassium permeability of a resting neuron increases above the resting permeability, what effect will this have on the transmembrane potential?
A) The inside of the membrane will become more positive.
B) The membrane will become depolarized.
C) There will be almost no effect on transmembrane potential.
D) The inside of the membrane will become more negative.
E) both B and D
