The diffusion potential for Na⁺ across a nerve cell membrane A)Favors its movement into the cell at resting potential B)Favors its movement out of the cell at resting potential C)Is equal and opposite to the electrical potential acting on sodium at resting potential D)Is in the same direction as the diffusion potential for potassium E)Both favors its movement into the cell at resting potential and is equal and opposite to the electrical potential acting on sodium at resting potential are correct

Question

Quizplus · Accepted Answer

At resting potential, the concentration gradient for Na⁺ favors its movement into the cell, as there is a higher concentration of Na⁺ outside the cell compared to inside.
