When an axon is at rest, positively charged sodium ions are

A) more concentrated inside the axon than outside.
B) equally concentrated inside and outside the axon.
C) more concentrated outside the axon than inside.
D) trapped inside small channels in the axon's membrane.

Question

Abdiwahab Hassan · Accepted Answer

Final Answer : C, Explanation :  When an axon is at rest, there is a higher concentration of positively charged sodium ions outside the axon than inside. This creates an electrical gradient where the inside of the axon is negatively charged relative to the outside. This difference in charge is known as the resting membrane potential.

A) more concentrated inside the axon than outside.
B) equally concentrated inside and outside the axon.
C) more concentrated outside the axon than inside.
