An action potential in a neuronal membrane differs from a graded potential in that A)An action potential requires the opening of Ca⁺² channels, whereas a graded potential does not B)An action potential is propagated without decrement, whereas a graded potential is not C)An action potential has a threshold and is an all-or-none phenomenon, whereas a graded potential does not have a threshold and is not all-or-none D)Both an action potential requires the opening of Ca⁺² channels, whereas a graded potential does not and an action potential is propagated without decrement, whereas a graded potential is not are correct E)Both an action potential is propagated without decrement, whereas a graded potential is not and an action potential has a threshold and is an all-or-none phenomenon, whereas a graded potential does not have a threshold and is not all-or-none are correct

An action potential is propagated without decrement and has a threshold, being an all-or-none phenomenon, while a graded potential does not have these characteristics.
