The reason that the inside of the axon is more negatively charged relative to the outside of the axon when in a resting state is because the
A) transmitter substances in the terminal button are negatively charged.
B) myelin sheath that surrounds the axon contains negative proteins.
C) ion transporters are negatively charged.
D) axon contains more negatively charged ions and fewer positively charged ions.
E) cell body transmits negatively charged ions to the axon.

Question

Quizplus · Accepted Answer

The inside of the axon is more negatively charged relative to the outside because it contains a higher concentration of negatively charged ions (such as chloride ions and proteins) and a lower concentration of positively charged ions (such as sodium and potassium), which is maintained by the sodium-potassium pump and other ion channels. This difference in charge creates the resting membrane potential.
