The following diagram is a model of the cell membrane. Though small, nonpolar molecules are usually able to pass freely across the cell membrane, larger molecules and ions can only enter and exit cells through carrier proteins or channel proteins.



Using the model above for reference, what effect would the removal of carrier proteins likely have on cell transport?
A.
The movement of sodium ions out of the cell would increase.
B.
The movement of glucose molecules into the cell would decrease.
C.
The concentration of glucose molecules outside of the cell would decrease.
D.
The number of protein channels in the membrane would increase.
