Nerve impulses travel along the neurons by the opening of channels that allow sodium ions to flow inward,followed by an outward flow of potassium ions.In order to ensure that the impulse may be produced at any time,sodium is actively transported out of the cell,and potassium is transported into the cell by the sodium/potassium pump.Which of the following types of work is performed by the sodium/potassium pump?
A)mechanical
B)electrical
C)concentration
D)synthetic
E)bioluminescent

Question

Quizplus · Accepted Answer

The sodium/potassium pump performs concentration work by actively transporting sodium out and potassium into the cell, which maintains the concentration gradients necessary for nerve impulses to travel along neurons.
