The electrical charge inside a neuron when it is in its resting state is approximately
A) +600 volts.
B) +60 millivolts.
C) -700 volts.
D) -70 millivolts.

Question

Quizplus · Accepted Answer

The electrical charge inside a neuron when it is in its resting state is approximately -70 millivolts, which is represented as -70mV. This is due to the presence of a higher concentration of negatively charged ions inside the cell and positively charged ions outside the cell, creating a potential difference across the cell membrane. This potential difference is known as the resting membrane potential. Option A and C are not correct because the value of electrical charge in volts is much higher than what is observed in the resting state of a neuron. Option B is also not correct because the value is too low.
