Vedclass · Answer

(A) The sodium-potassium pump is a membrane protein that maintains the resting membrane potential of a neuron.It functions via active transport,which requires energy in the form of $ATP$.For every cycle of the pump,$3 Na^+$ ions are transported out of the cell,and $2 K^+$ ions are transported into the cell against their respective concentration gradients.Therefore,option $A$ is the correct description.
