- - - - 1-The magnitude of the concentration gradient. ~~> Directly proportional
      - 2-The permeability of the plasma membrane to a substance.~~> Directly proportional
      - 3-The surface area of the membrane across which diffusion takes place ~~> Directly proportional
      - 4-The molecular weight of a substance ~~> Inversely proportional
      - 5-The distance through which diffusion takes place ( thikhness) ~~> Inversely proportional
    - - step 1 Conformation x of carrier (binding sites exposed to ECF) Molecule to be transported binds to carrier
      - step 2 On binding with molecules to be transported, carrier changes its conformation
      - step 3 conformation Y of carrier (binding sites exposed to ICF )
        Transported molecule detaches from carrier
      - step 4 conformation X of carrier (binding sites exposed to ECF )
        After detachment , carrier reverts to original shape
- - - - The water and soluble concentrations are equel ..
      - No further net diffusion
  - - - The water and soluble concentrations are not equel .
