Explain the reason that the resting potential for neurons isaround -70mV. Be sure to include the roles of the K+ and Na+concentration gradients, electrical forces, passive ion channelsand the relative permeabilities of K+ and Na+. Now, say that analien race was discovered from a distant galaxy. Their cells have ahigher concentration of Na+ inside than outside their cells and ahigher concentration of K+ outside than inside. If this raceâ€™sneurons otherwise had the same relative permeability to K+ and Na+at rest that Earth organisms have, what might an approximate valueof the resting potential of these alienâ€™s cells be? Why?

There is a stable separation ofcharges across the cell membrane called the resting potentialThere are more positive charges on the outside of the membrane andmore negative charge along the inside of the cell ie anions aredominant inside the cell and cations are predominant outside thecell Keeping the net charge outside the cell as a reference with 0mV it is found that about 70 milli volt is present inside themembrane This is a common resting membrane potential for a neuronResting membrane potential of neurone is related to concentrationdifferences called See Answer
