Decreased extracellular K⁺ levels cause

A) cells to become more excitable.
B) hyperpolarization of plasma membranes.
C) more action potentials to be generated.
D) increased permeability of plasma membranes.
E) hypopolarization of plasma membranes.

Hyperpolarization

Increase in the charge difference across the plasma membrane; causes the charge difference to move away from 0 mV.

Hypopolarization

Change in the electric charge difference across the plasma membrane that causes the charge difference to be smaller or move closer to 0 mV.

Extracellular

Located or occurring outside a cell or cells.
