Practice question
Question
Choose the correct range of membrane potential, the voltage across a membrane.
Explanation
Resting membrane potentials typically range from -20 mV to -200 mV depending on cell type, established by Na+/K+ ATPase and selective permeability to K+. Neurons near -70 mV, plant cells more negative, maintaining electrochemical gradient essential for excitability.
