Ion transporters are "linked" together-not physi- cally, but as a consequence of their actions. For example, cells can raise their intracellular pH, when it becomes too acidic, by exchanging external
for internal
using a
antiporter. The change in internal
is then redressed using the
pump. a. Can these two transporters, operating together, normalize both the
concentrations inside the cell? b. Does the linked action of these two pumps cause imbalances in either the
concentration or the mem- brane potential? Why or why not?
