Some cells express aquaporin proteins—they are channel proteins that facilitate the flow of water molecules through the plasma membrane. What regulates the rate and direction of water diffusion across the membrane? Select one: a. solute concentrations on either side of the membrane b. resting membrane potential c. availability of ATP d. aquaporin pore size
