Which of the following occurs when a membrane is stimulated due to opening of chemically gated Na⁺ channels? A)An impulse is propagated. B)A graded potential is established. C) An action potential is established. D) The voltage becomes more negative.

Question

Quizplus · Accepted Answer

When chemically gated Na+ channels open, ions flow into the cell, causing a depolarization of the membrane. This creates a graded potential, which may or may not be strong enough to reach the threshold for generating an action potential.
