You have a planar bilayer with equal amounts of saturated and unsaturated phospholipids. After testing the permeability of this membrane to glucose, you increase the proportion of unsaturated phospholipids in the bilayer. What will happen to the membrane's permeability to glucose?
A) You can't predict the outcome. You simply have to make the measurement.
B) Permeability to glucose will stay the same.
C) Permeability to glucose will decrease.
D) Permeability to glucose will increase.
