Which of the following is TRUE of a graded potential?
A) A stimulus causes ion channels to open which changes membrane permeability
B) The potential is propagated with a constant magnitude
C) The potential is all-or-none
D) No summation of potentials occurs

Question

Quizplus · Accepted Answer

Graded potentials occur when a stimulus causes ion channels to open, changing the membrane permeability. Unlike action potentials, they are not all-or-none, can vary in magnitude, and can summate.
