MATCHING Indicate the direction that the force in question tends to move the involved ion under the stated conditions by writing the appropriate letter in the blank, using the following answer code: -concentration gradient for Na⁺ at threshold potential A)This force tends to move the involved ion out of the cell. B)This force tends to move the involved ion into the cell.

Question

Quizplus · Accepted Answer

At threshold potential, the concentration gradient for Na+ is higher outside the cell than inside, so there is a net movement of Na+ into the cell. Therefore, the force in question (concentration gradient for Na+) tends to move Na+ into the cell.
