WebThe resting potential of a neurone is -70 mV, which means that it's more negative in the cytoplasm than in the tissue fluid. In the membrane there are sodium-potassium pumps which work using active transport and so need ATP. There are also sodium channel proteins and potassium channel proteins in the membrane which rely on facilitated diffusion.
