Myelinated axons consume less energy because:
A)Action potentials occur faster
B)The sodium potassium pumps have less work to do
C)Graded potentials do not consume energy
D)The sodium potassium pumps are more efficient on these neurons

Question

Quizplus · Accepted Answer

Myelinated axons consume less energy primarily because action potentials are only generated at the nodes of Ranvier, rather than along the entire length of the axon. This means that the sodium-potassium pumps, which work to restore the ion balance after an action potential, have less work to do, thereby conserving energy.
