Which of the following is responsible for maintaining the difference in ion concentration across the membrane of a nerve cell?
here are choices
the sodium-potassium pump
the action potential
the depolarization of the membrane
the ion channels in the membrane
I think it is the sodium-potassium pump. Am I correct?
The sodium-potassium pump...three NA in, two K out causes difference in ion concentration.
you are correct
