Explain the function of sodium-potassium ion pumps
A) They generate ATP for the cell during the electron transport chain when hydrogen ions move in a process known as chemiosmosis. B) The sodium-potassium ion pump binds acetylcholine across the synaptic cleft to generate an action potential at the sarcolemma. C) The sodium-potassium ion pump allows facilitated diffusion of potassium during the repolarization of a muscle cell. D) The sodium-potassium ion pump allows facilitated diffusion of sodium during the depolarization of a muscle cell. E) The sodium-potassium ion pump maintains the resting membrane potential of a cell by exporting three sodium ions out in exchange for two potassium ions entering the cell.
