Which of the following correctly describes a graded potential?
A) It has a depolarization, repolarization, and hyperpolarization phase.
B) It can have amplitudes of various sizes.
C) It travels long distances.
D) It is initiated by voltage changes in the membrane.

Question

Quizplus · Accepted Answer

Graded potentials are small changes in membrane potential that can vary in amplitude depending on the strength of the stimulus. They do not have distinct phases like action potentials and do not travel long distances like action potentials. They are initiated by a stimulus causing a change in ion flow across the membrane, but not necessarily by voltage changes in the membrane.
