Cellular Transport. Facilitated diffusion involves carrier molecules that passively transport solutes down a concentration gradient. Factors that affect rate are the amount of pressure, the size of pores in the filter, and the availability of carrier protein. The substances involved for all cells are glucose and amino acids.
