Question

multiple choice question because the cell membrane is highly permeable to ____ diffusion of these ions from inside to outside of a cell contributes to the negative charge that exists just inside of the cell membrane at resting membrane potential. chloride sodium potassium calcium

Explanation:

At resting - membrane potential, the cell membrane is highly permeable to potassium ions. The outward diffusion of potassium ions from the inside to the outside of the cell contributes to the negative charge inside the cell. Chloride ions also contribute to the resting - potential but not as significantly as potassium. Sodium and calcium are less permeable at resting - membrane potential compared to potassium.

Answer:

C. potassium
