Which of the following will cause the plasma membrane to hyperpolarize when at its resting membrane potential? A) An inflow of Na⁺ B) An inflow of K⁺ C) An inflow of Ca²⁺ D) An inflow of Cl⁻ E) An outflow of Cl⁻

Question

Quizplus · Accepted Answer

Hyperpolarization occurs when the membrane potential becomes more negative. An inflow of Cl^- (chloride ions), which are negatively charged, into the cell would increase the negative charge inside the cell, leading to hyperpolarization.
