When a neuron is in the resting potential state:
A)it is unable to activate.
B)it has a negative electrical charge of about 7 volts.
C)the fluid within the axon has a larger concentration of potassium ions than the fluid surrounding the axon.
D)the ion channels are open.

Quizplus · Accepted Answer

During the resting potential state of a neuron, the fluid within the axon has a larger concentration of potassium ions than the fluid surrounding the axon. This creates an electrical gradient that maintains the negative charge inside the cell. The ion channels are closed during this state to maintain the resting potential. The negative charge is not 7 volts, but rather around -70 millivolts. The neuron is able to activate from this state through a process called depolarization.
