Equilibrium Potential (Cl-)


The figure shows a cell with the following labeled:

* Chloride (Cl-) ion concentrations (measured in mg/L) inside and outside the cell

* Membrane potential (-70 mV)

* Cl- channel

a) In this situation there is net movement of Cl- ions out of the cell through the Cl- channel (as indicated by the arrow). What would have to change to cause net movement of Cl- INTO the cell? Identify as many ways as you can.

b) Explain how the ways you identified above cause Cl- to move INTO the cell.
