6) In a postsynaptic neuron, the opening of ionotropic non-specific cation channels causes depolarisation of the cell membrane because a. these ion channels only allow the passage of potassium (K+) ions b. the efflux of calcium (Ca²+) through these channels causes shunting inhibition C. these ion channels only allow the passage of sodium (Na+) ions d. the electrochemical force driving sodium (Na+) ions into the cell is greater than the electrochemical force driving potassium (K+) ions out of the cell e. magnesium (Mg²+) ions that normally block these ion channels are expelled from the channel pore and allow potassium (K*) ions to leave the cell
