Which of the following statements are applicable and which aren’t? A. Diffusion of a solute through a membrane is considerably quicker than diffusion of the same solute through a water layer of equal thickness. b. A single ion, such as K+, can diffuse through more than one type of channel. c. Lipid-soluble solutes diffuse more readily through the phospholipid bilayer of a plasma membrane than do water-soluble ones. d. The rate of facilitated diffusion of a solute is limited by the number of transporters in the membrane at any given time. e. A common example of co-transport is that of an ion and an organic molecule.
