Match the result, labelled a. or b., with the force and involved ion in question. (Options may be used more than once or not at all.)
-electrical gradient for Na⁺ at resting potential
A)The ion tends to be moved into the cell by this force.
B)The ion tends to be moved out of the cell by this force.

Question

Quizplus · Accepted Answer

At resting potential, the electrical gradient for Na⁺ is such that it tends to move into the cell. This is because the inside of the cell is negatively charged relative to the outside, and Na⁺ has a positive charge. Therefore, the positively charged Na⁺ ion is attracted to the negative charge inside the cell, and tends to move in that direction.
