- - - - substance has more concentration than solution outside of it
        
        deflates
    - - solution with equal concentration
        
        equal
    - - solution has more concentration than substance inside it
        
        explodes
- - - - glycoprotein acts as identification tags that are recognized by other cells
    - - proteins of adjacent cells hook together in junctions
    - - messenger protein have a binding site with a protein with a specific shape the fits shape of a chemical messenger
    - - microfilaments bonded to membrane proteins-->helps maintain cell shape
    - - protein built into membrane is an enzyme with its active site exposed to substances in adjacent solution
    - - protein adhere to ECM coordinate extracellular and intracellular change
    - - hydrophilic channel across the membrane that is selective for a specific solute.
- - - - changes the shape and allow protein to move to other side
  - - - diffuse through membrane with help from transport protein
      - channel proteins--> hydrophilic channel for particles to pass through
      - carrier protein--> change shape to move particles across membrane
    - - solutes move down concentration gradient
      - particles (nonpolar, small) to diffuse across a semi-permeable membrane)
