Vedclass · Answer

(A) The sodium-potassium pump ($Na^+/K^+$-ATPase) is an active transport mechanism that maintains the resting membrane potential of a neuron.It functions by pumping $3Na^+$ ions out of the cell and $2K^+$ ions into the cell against their respective concentration gradients.This process requires energy in the form of $ATP$ hydrolysis.Therefore,the correct transport ratio is $3Na^+$ outwards for $2K^+$ into the cell.

For the maintenance of ionic gradients across the resting membrane,the sodium-potassium pump transports:
