When a membrane is stimulated due to opening of either chemically-gated Na⁺ or Cl^- channels: A) An impulse is propagated. B) A graded potential is established. C) An action potential is established. D) The voltage becomes more negative. E) Threshold is reached.

Question

Quizplus · Accepted Answer

Chemically-gated ion channels, such as Na⁺ or Cl^-, can lead to the establishment of a graded potential. Graded potentials are changes in membrane potential that vary in amplitude, and do not reach the threshold for an action potential.
