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 is initiated by voltage changes in the membrane
D) it travels long distances

Question

Quizplus · Accepted Answer

Graded potentials are local changes in membrane potential that can have varying amplitudes depending on the strength of the stimulus. They do not have distinct depolarization, repolarization, and hyperpolarization phases like action potentials, and they are not capable of traveling long distances like action potentials can. They are typically initiated by a stimulus that causes the opening or closing of ion channels in the membrane, resulting in a change in membrane potential.
