Im having a hard time understanding how the interaction of the concentration gradient, the elctrical gradient, and the existence of the other ions play into and interact with eachother to result in the membrane potential we know and love.
So as i understand it,
-More potassium inside than outside.
-More sodium outside than inside.
-This concentration difference is maintained by the ATP sodium potassium pump (3 Na+ out, 2 K+ in)
-BUT the negative membrane potential difference comes not...
Can someone explain the basis of the membrane potential? (conc gradient + electric + ion interaction
