Crossing a cell membrane by simple diffusion can be distinguished from facilitated diffusion by which of the following: Select all that apply Simple diffusion moves molecules down a concentration gradient while facilitated diffusion moves molecules up a concentration gradient Simple diffusion does not require membrane proteins; facilitated diffusion requires specific membrane proteins Simple diffusion does not require energy; facilitated diffusion requires energy Simple diffusion is not saturable; facilitated diffusion rates are limited by the number of functional membrane proteins and can be saturated
