A graded hyperpolarization of a membrane can be induced by A)increasing its membrane's permeability to Na⁺. B)decreasing its membrane's permeability to H⁺. C)decreasing its membrane's permeability to Cl^-. D)increasing its membrane's permeability to Ca²⁺. E)increasing its membrane's permeability to K⁺.

Question

Quizplus · Accepted Answer

Increasing the membrane's permeability to K⁺ allows more K⁺ ions to leave the cell, making the inside more negative and causing hyperpolarization.
