An electrical gradient
A)favors the movement of K+ out of the cell at resting potential
B)favors the movement of Na+ into the cell at resting potential
C)opposes the concentration gradient for Na+ at the equilibrium potential for Na+
D)favors the movement of Cl- out of the cell at resting potential
E)prevents the active transport of K+ into the cell

Question

Quizplus · Accepted Answer

An electrical gradient favors the movement of ions from an area of higher charge to an area of lower charge. At resting potential, the inside of the cell is negatively charged relative to the outside of the cell. This electrical gradient favors the movement of positively charged ions, such as Na+, into the cell.
