Decreased extracellular potassium levels cause
A)cells to become more excitable.
B)hyperpolarization of cell membranes.
C)more action potentials to be generated.
D)increased permeability of cell membranes.
E)hypopolarization of cell membranes.

Question

Quizplus · Accepted Answer

Decreased extracellular potassium levels lead to hyperpolarization of cell membranes because the resting membrane potential becomes more negative, making it harder for cells to reach the threshold needed to generate action potentials.
