The Nernst Equation Calculates the Membrane Equilibrium Potential to Be

question 120

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.
