Question

What is the typical voltage of the resting membrane potential in a neuron?

• A. +70 mV
• B. -70 mV
• C. 0 mV
• D. +30 mV

Hint:

The resting potential is maintained by the sodium-potassium pump (Na⁺/K⁺ ATPase), which moves sodium out and potassium in to keep the cell's charge difference stable.
