The figure shows a plant cell with the following labeled:
● potassium (K+) ion concentrations (measured in mM) inside and outside the plant cell
● membrane potential (-95 mV)
● K+ channel
a) In this situation there is net movement of K+ ions out of the plant cell through the K+ channel (as indicated by the arrow). What would have to change to cause net movement of K+ INTO the plant cell? Identify as many ways as you can.
b) Explain how the ways you identified above cause K+ to move INTO the cytoplasm of the plant cell.
