The investigator applies a brief electrical stimulus that causes the potassium channels to open. there are no hco3- channels, thus pk+ = 1 and phco3- = 0. first, what is the potential difference between compartments a and b after the system reaches equilibrium? second, to estimate the potential difference do we need to be concerned about a change in potassium concentration as the concentration gradient drives k+ from a to b? why or why not?
