9.  Cell Membrane Lipids
◦ Phospholipid bilayer
 Hydrophilic – water loving
 Hydrophobic – water repel

10.  Cell Membrane Proteins
◦ Structural Proteins
 Support and shape
◦ Transport Proteins
 Transport molecules
◦ Glycoproteins
 Cell communications

11.  Refers to the movement of different materials in
and out of the cell.
 CAN ALL MATERIALS PASS THROUGH THE
CELL MEMBRANE?

13.  Movement of biochemical substances across
membranes
 It does not require an input of chemical
energy
