Nerve impulses travel along the neurons by the opening of channels that allow so

Question

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? mechanical electrical concentration synthetic bioluminescent 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.

Explanation / Answer

The sodium-potassium pump of the nerve cells is involved in the maintenance of membrane potential of the area. It is involved in bringing the cell back to resting membrane potential.The pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from the cell and two potassium ions are imported into the cell along with hydrolysis of one ATP. Hence, the type of work performed by the pump is Electrical.
