Graded potentials
A) are often all- or- none.
B) cause repolarization.
C) produce an effect that increases with distance from the point of stimulation.
D) may be either a depolarization or a hyperpolarization.
E) produce an effect that spreads actively across the membrane surface.

Question

Quizplus · Accepted Answer

Graded potentials can result in either depolarization or hyperpolarization, depending on the type of ion channels that are activated and the ions that flow through them. They are not all-or-none, do not cause repolarization, and their effect decreases with distance from the point of stimulation. They spread passively, not actively, across the membrane.
