A) Different types of aquaporin proteins allow different rates of water diffusion.
B) Different aquaporin proteins are localized to different membranes in the cell.
C) Different types of aquaporin proteins are produced in different cell types.
D) Different types of aquaporin proteins alter the amount of water retention within a cell.
E) Different aquaporin proteins have different functions within the cells.
