Absorption, Distribution, and Storage of Chemicals Methods of chemical transportation. One of the mechanisms for moving chemicals through the cell membrane is passive diffusion. Passive diffusion of a chemical is based on the difference in concentration of the chemical between the outside of the cell as compared to inside the cell.
