During one cycle, the sodium-potassium pump binds and moves: a) 2 Na+ into and 2 K+ out of the cell b) 3 Na+ out of and 2 K+ into the cell c) 2 Na+ out of and 3 K+ into the cell d) 1 Na+ into and 2 K+ out of the cell e) 3 Na+ into and 3 K+ out of the cell

Step 1
It works by binding to three sodium ions inside the cell and two potassium ions outside the cell. Then, the pump uses ATP to change its shape and move the sodium ions out of the cell and the potassium ions into the cell. This process is called "active transport" Show more…

The Na-K pump functions to pump: sodium and potassium ions into the cell sodium and potassium ions out of the cell sodium and potassium ions in both directions across the cell membrane sodium ions into the cell and potassium ions out of the cell sodium ions out of the cell and potassium ions into the cell
Sri K.
The major function of the sodium-potassium pump is to: a. pump Na+ into and K+ out of the cell. b. generate the resting membrane potential. c. maintain the concentration gradients of Na+ and K+ across the plasma membrane. d. oppose any tendency of the cell to undergo hyperpolarization.
