Which of the following statements about action potentials is FALSE?
A)All action potentials for a given neuron are identical in magnitude.
B)All action potentials for a given neuron are identical in duration.
C)Action potentials are propagated down the length of the axon.
D)Movement of ions during the action potential occurs mostly through the sodium pump.
E)The frequency of action potentials,not their size,is the meaningful signal.

Question

Quizplus · Accepted Answer

Movement of ions during the action potential occurs mostly through ion channels, specifically voltage-gated sodium and potassium channels. The sodium/potassium pump plays a role in maintaining the concentration gradients of these ions, but it does not contribute significantly to the movement of ions during action potentials.
