Compared to a graded potential,an action potential is _______ and _______.
A) larger;is an all-or-none event
B) smaller;is an all-or-none event
C) larger;can have a range of values
D) smaller;can have a range of values
E) larger;does not propagate along the axon

Question

Quizplus · Accepted Answer

An action potential is larger because it involves a rapid depolarization of the membrane potential. It is an all-or-none event because it either occurs fully or not at all, and there is no intermediate level of depolarization. Graded potentials, on the other hand, can vary in size and can be either depolarizing or hyperpolarizing.
