The sodium-potassium pump ____
|
|
Sends (Na+) into the cell
|
|
|
Sends (K+) into the cell
|
|
|
Exchanges (K+) & (Na+) during depolarization
|
|
|
Exchanges (K+) & (Na+) during hyperpolarization
|
Explanation:
Detailed explanation-1: -The sodium-potassium pump is an active transport pump that exchanges sodium ions for potassium ions.
Detailed explanation-2: -The sodium–potassium pump mechanism moves 3 sodium ions out and moves 2 potassium ions in, thus, in total, removing one positive charge carrier from the intracellular space (see Mechanism for details).
Detailed explanation-3: -The Na+/K+-ATPase pumps 3 sodium ions out of cells while pumping 2 potassium ions into cells. Both cations move against their concentration gradients.
