The Nernst Equation Calculates the Membrane Equilibrium Potential to Be

Multiple Choice

The Nernst equation calculates the membrane equilibrium potential to be approximately -80 mV,which is slightly different from the measured resting neuron potential of -60 to -70 mV.The difference most likely occurs because

A) the membrane equilibrium potential is not a resting potential.
B) the equation assumes only one ion (K⁺) can move across the membrane.
C) the equation assumes only one ion (Na⁺) can move across the membrane.
D) the sodium‒potassium pump works differently in neurons than in other cells.
E) the temperature of cells is different from the temperature used in the equation.
