The figure shows an animal cell with the following labeled:
● Potassium (K+) ion concentrations (measured in mM) inside and outside the animal cell
● Membrane potential (-70 mV)
● K+ channel
a) In this situation, there is net movement of K+ ions out of the animal cell through the K+ channel (as indicated by the arrow). What would have to change to cause net movement of K+ INTO the animal cell? Identify as many ways as you can.
b) Explain how the ways you identified above cause K+ to move INTO the animal cell.
