Which of the following is false regarding the membrane potential

Asked by admin @ in Biology viewed by 319 People

Which of the following is FALSE regarding the membrane potential?A) The resting membrane potential is maintained by solely by passive transport processes.B) In their resting state, all body cells exhibit a resting membrane potential.C) The resting membrane potential is determined mainly by the concentration gradients and differential permeability of the plasma membrane to K+ and Na+ions.D) The resting membrane potential occurs due to active transport of ions across the membrane due to the sodium-potassium pump.

Answered by admin @


The statement indicating that the resting membrane potential is maintained solely by passive transport processes is FALSE (Option A).

  • Resting membrane potential is the potential of the cell membrane that results from separating different concentrations of ions inside and outside the cell.

  • This resting membrane potential is maintained by the mechanism of active transport of ions against a concentration gradient.

  • In neurons, sodium-potassium pumps are responsible for maintaining the resting membrane potential.

  • These pumps use the energy released by the hydrolysis of ATP in order to move ions across the cell membrane against an electrochemical gradient.

In conclusion, the statement indicating that the resting membrane potential is maintained solely by passive transport processes is FALSE (Option A).
