    (Ans-18), Sodium has fast gates because it's moving under the influence of two gradients (conc. and electrical) whereas potassium moves against (electrical) one and in favor(conc.) of another gradient thus it can be managed easily with slow gate.

    According to goldman equation increase of Cl- inside the cell will cause depolarization, but it is impossible because chloride ion is negatively charged so it should hyperpolarize the cell. Of course Cl-influx will cause hyperpolarization but what if I put the chloride anion inside the cell? Where am I wrong in this deduction?

    When considering Cl- in the Goldman eq, you have to determine the inverse of the standard setup of the equation. To explain further, the concentration outside of the cell will be in the denominator of the equation rather than the numerator as the positive ions are expressed. Vice versa for the concentration within the cell.
