The outside of a neuron is positively charged at resting potential.Why don't negative ions exit from the cell to normalize charge across the membrane?
A)The positive charge outside the cell repels negative ions.
B)There are no negative ions inside the cell.
C)All of the chloride ions are already outside the cell.
D)The negative charge inside the cell is carried by large proteins that cannot diffuse through the membrane.
