C)double process
D)all-or-none process

Question

Quizplus · Accepted Answer

The firing of an action potential is an all-or-none process, which means that there is a threshold level of depolarization that must be reached in order for the action potential to be generated. Once this threshold is met, the action potential will fire at full strength, regardless of the strength of the initial depolarization. This is why action potentials are often described as being "digital" signals, with either the presence or absence of the signal being important, rather than the magnitude of the signal.
