c)Is important for maintaining a constant cell volume 6. c)-60 mV 7. d)Is used to deliver material into the extracellular space 8. b)Retrieve elements of the cell membrane after exocytosis The cell membrane limits the diffusion of solutes dissolved in water. However, the water molecules themselves can freely diffuse across the cell membrane through channel proteins called aquaporins. An aquaporin is a transport protein in a cell membrane that allows for osmosis, the movement of water back and forth.
