Identify the FALSE statement.
A) Under normal conditions, all action potentials in a given cell are identical.
B) Between nodes of Ranvier, signal conduction is decremental.
C) The amplitude of the action potential depends on the amplitude of the graded potential that precedes it.
D) The voltage-gated sodium and potassium channels begin to open during the depolarization.

Question

Quizplus · Accepted Answer

The amplitude of the action potential is not directly proportional to the amplitude of the graded potential that precedes it. Rather, the action potential is an all-or-nothing response that is either initiated or not, depending on whether the threshold potential is reached.
