Which of the following situations will lead to hyperpolarization?
A) increase the permeability of the plasma membrane to Na+ ions
B) decrease the permeability of the plasma membrane to K+ ions
C) decrease the permeability of the plasma membrane to chloride ions
D) any positive ion entering the cell
E) None of these situations will lead to hyperpolarization.

Question

Quizplus · Accepted Answer

Hyperpolarization occurs when the inside of the cell becomes more negative relative to the outside. None of the given options would lead to hyperpolarization; increasing Na+ permeability or any positive ion entering the cell would depolarize it, while decreasing K+ or Cl- permeability would not cause hyperpolarization.
