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.)
-concentration gradient for K⁺ 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

The concentration gradient for K⁺ at resting potential causes the ion to be moved out of the cell. This is because there is a higher concentration of K⁺ inside the cell than outside, and so the ion will tend to move down its concentration gradient from the inside to the outside of the cell. This outward movement is balanced by the electrostatic force due to the membrane potential, which tends to hold the K⁺ inside the cell.
