      Potential difference across resting membrane is negatively charged. This is due to differential distribution of the following ions. (a) and ions        (b) and ions    (c) and ions    (d) and ions

    Answer:

                    (a) The ion gated channels on the neurolemma control the movement of and ions on both inner and outer side of nerve cell. and ions are not related with nerve excitation rather are involved in other biological functions.  ions are related to muscle metabolism where ions act as a cofactor in some reactions. ion channels are important for setting cell resting membrane potential, trans epithelial salt transport, and the acidification of internal and extracellular compartments.
