Which of the following statements about the resting membrane potential is TRUE? A) It is normally equal to zero volts. B) The inside of the membrane is positively charged compared to the outside. C) It results, in part, from the concentration gradients for Na⁺ and K^+. D) It is due in part to the presence of extracellular proteins.

Question

Quizplus · Accepted Answer

The resting membrane potential results from the concentration gradients of ions such as Na+ and K+. The inside of the membrane is negatively charged compared to the outside, which creates a potential difference across the membrane. The resting membrane potential is typically around -70 millivolts, not zero volts. Extracellular proteins do not play a significant role in establishing the resting membrane potential.
