8. Equilibrium potential of different ions across the plasma membrane of a cell is calculated by the Nernst equation. (a) The equilibrium potential of sodium ion is +60 mV. What does it mean? (1 mark) (b) The depolarization phase of action potential is caused by sodium influx. List Two reasons why the peak of action potential is not equal to the equilibrium potential of sodium ions and start to drop after +30 mV. (4 marks)
