The sodium pumps of nerve cells rely on the process of:
A)diffusion
B)facilitated diffusion
C)active transport
D)filtration

Question

Quizplus · Accepted Answer

The sodium pumps in nerve cells rely on active transport, which requires energy to move substances against their concentration gradient. The pumps use ATP to transport sodium ions out of the cell and potassium ions into the cell, maintaining the balance of ions necessary for nerve impulses. Diffusion, facilitated diffusion, and filtration do not require energy and are not the processes used by sodium pumps.
