I dont understand how the sodium-potassium pump changes the cell from hyperpolarisation to resting potential if the sodium-potassium pump makes the cell more negative. Doesnt the cell need to become more positive?
Cheers for ur help

no, the cell needs to become more negative
resting potential is like -70mV, action potential is +40mV, so it needs to go back down, more negative
