Which of the following statements about resting potential is true? A resting membrane allows much more sodium than potassium to diffuse across. The concentration of sodium is much higher inside the cell than outside. The resting potential exists because of differences in glucose concentration inside and outside the cell. The sodium-potassium pump contributes to the resting membrane potential.

Which of the following statements about resting membrane potential is not true? (a) The resting membrane potential for most animal cells is 0 mV, because the positive and negative ions are in balance. (b) The resting membrane potential for most animal cells is positive, because Na+ ions are so plentiful inside cells. (c) The resting membrane potential for most animal cells is negative, because the inside of the cell is more negatively charged than the outside of the cell. (d) At the resting membrane potential, no ions enter or exit the cell.

Which of the following statements about the resting membrane potential of a cell is true? A. There is a higher concentration of potassium ions lining the inside of the cell membrane than outside the membrane B. There is a higher concentration of sodium ions within the interstitial fluid than the cytosol C. Potassium ion is attracted to the negative charges inside the cell D. Sodium ion is attracted to the negative charges inside the cell E. An influx of extracellular potassium ions into the cell will cause the membrane potential to become more positive F. All of the above statements are true
