Diffusion and osmosis - Coggle Diagram

- - - - P = permeability coefficient
        A = surface area
        C = conc.
    - - D = diffusion coefficient
        A = surface area
        CM = conc. within the membrane
        X = thickness
  - - - Kp = partition coefficient
        D = diffusion coefficient
        X = thickness
    - - frictional effects
        molecular size/shape
        membrane viscosity
      - lipid solubility
        high Kp increases P
        low Kp decreases P
      - unstirred layers
        additional layers like mucus that add thickness
      - Charge and hydrogen bonding
