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 inside of the membrane will become more negative.
C)There will be almost no effect on transmembrane potential.
D)The membrane will become depolarized.
E)The membrane will depolarize to threshold.

An increase in potassium permeability means more potassium ions will leave the cell, leading to a net loss of positive charge from the intracellular fluid, and making it more negative. This will result in hyperpolarization, making the transmembrane potential more negative.
