Question

how does the sodium - potassium pump function?
a by using energy to transport three sodium ions out of the cell and bring two potassium ions into the cell.
b by using energy to transport two sodium ions out of the cell and bring three potassium ions into the cell.
c by using energy to transport three sodium ions out of the cell and bring three potassium ions into the cell.
d by using energy to transport two sodium ions out of the cell and bring two potassium ions into the cell.

Explanation:

The sodium - potassium pump is an active - transport mechanism. It uses energy (ATP) to move three sodium ions out of the cell and two potassium ions into the cell, maintaining the electrochemical gradient.

Answer:

A. By using energy to transport three sodium ions out of the cell and bring two potassium ions into the cell.
