A question from the Pearson lab: Predict what will happen to the membrane potential if the extracellular Na+ concentration is decreased: membrane potential will get more positive membrane potential will get more negative nothing-Na+ does not affect the membrane potential. Question 6 What effect does increasing extracellular K+ have on the diffusion of K+ out of the cell? It increases the net diffusion of K+ out of the cell. It decreases the net diffusion of K+ out of the cell. The cell becomes more active The cell becomes more inactive
Predict how an increase in the permeability of the membrane to specific ions like sodium, potassium and chloride will influence the resting membrane potential (RMP). Discuss the changes in the resting membrane potential for each ion separately.
