Water diffuses through certain organs such as the kidneys and bladder much faster than would occur by passive diffusion through a lipid bilayer alone.What accounts for this more rapid rate of water transport in these organs?
A)The composition of lipids changes to promote water transport.
B)Presence of aquaporin channels for facilitated diffusion of water.
C)Presence of a water pump.
D)Presence of an ATP-driven enzyme for water transport.
E)The presence of molecules that bind water and change its membrane permeability properties.
