During neuronal signaling,a change in membrane potential will cause sodium channels to open and let Na⁺ ions diffuse down their concentration gradient into the cell.Which of the following helps establish the concentration gradient necessary for this process to occur? A)Na⁺/K⁺ channel B)voltage-gated Na⁺ channel C)Na⁺ symporter D)Na⁺/K⁺ pump

Question

Quizplus · Accepted Answer

The Na+/K+ pump is responsible for establishing and maintaining the concentration gradient necessary for the Na+ channels to open and allow Na+ ions to flow into the cell during neuronal signaling. It continuously pumps Na+ ions out of the cell and K+ ions into the cell, ensuring that there is a higher concentration of Na+ ions outside the cell and a higher concentration of K+ ions inside the cell. This gradient creates the necessary electrochemical potential for the movement of Na+ ions into the cell through voltage-gated channels.
