Which of these statements describes the concentration gradient for Na⁺ A)It favours the movement of Na⁺ into the cell at resting potential. B)It favours the movement of Na⁺ out of the cell at resting potential. C)Na⁺ equilibrium potential is -90 mV. D)Na⁺ equilibrium potential is -60 mV.

Question

Quizplus · Accepted Answer

The concentration gradient for Na⁺ at resting potential favors its movement into the cell because the concentration of Na⁺ is higher outside the cell than inside. This creates a natural drive for Na⁺ to enter the cell to balance the concentration differences.
