Anyone know what would happen to a resting membrane potential if the concentration of large intracellular anions that are unable to cross the membrane is experimentally increased?  PhysioEx Excersie 3, activity 1

The resting membrane potential would become more negative because there would be more negative anions inside the cell.

Makes sense.  So if a channel was blocked and ions were unable to move in or out, the RMP would stay the same I'm assuming.  That would only make sense because nothing is moving in or out.  Where as if anions can't move out of the cell from a high concentration to a low outside of membrane, then that is why the RMP would become more negative?
