1 In the resting neuron what is true about the K gradient Inside the neuron the K ions will have a higher concentrations as compared to the outsideHence making a gradient of potential across the cell membrane70 mVThis is by the action of membrane active transport systemNaK pump which pumps Na out of the cell and K into it 2 A graded potential causes large or small movements of ions A graded potentail is the initiial potential gradient that is created in a resting nerve dendrite terminal to make the depolarization of the membrane for the first timeThe Neurotransmitter binds to the receptor of Na and Ca2 and cause the See Answer
