Why is the resting state of a neuron (labeled A) negative? A. Because the undershoot (labeled D) has not been corrected yet. B .By convention, we call the resting state negative so that the spike is positive, which is more intuitive. C.Because there are more positive ions (Na+ and K+) outside the cell than inside the cell. D. Because all the negative ions are trapped inside the cell’s impermeable membrane. E.Because of the negative environment in its Twitter feed.

Answer

• Because there are more positive ions (Na+ and K+) outside the cell than inside the cell.
  Explanation:
  The cell moves sodium and potassium ions in opposite directions across the cell. Even when the concentration gradient gets to equilibrium between the inside and the outside, the cell continues to move three sodium ions out of the cell, with an exchange of two potassium ions which enters the cell. This means that with time, there will be more positive ions out of the cell than in the inside.
