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.
