B) An inflow of potassium
C) An inflow of calcium
D) An inflow of chloride
E) An outflow of chloride

Question

Quizplus · Accepted Answer

Hyperpolarization of the plasma membrane occurs when the membrane potential becomes more negative than the resting membrane potential (RMP). An inflow of chloride ions (Cl-) into the cell, which are negatively charged, would contribute to making the inside of the cell more negative, thus hyperpolarizing the membrane.
