Which is incorrect?a. Diffusion of a solute through a membrane is considerably quicker thandiffusion of the same solute through a water layer of equal thickness.b. A single ion, such as K1, can diffuse through more than one type ofchannel.c. Lipid-soluble solutes diffuse more readily through the phospholipidbilayer 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 cotransport is that of an ion and an organic molecule.
