Biology Lecture Notes Y. Nagah 1 | P a g e Biology Lecture Notes (STEMer’s guide) 2024 Lecture (3) Resting potential – Action potential Mr. Youssef Nagah Biology Lecture Notes Y. Nagah 2 | P a g e Ion pump and ion channels establish the resting potential of a neuron As you know, ions are unequally distributed between the interior of cells and the fluid that surrounds them. As a result, the inside of a cell is negatively charged relative to the outside. Because the attraction o...
