3. Objectives To identify the components of the cell membrane
To explain what role each macromolecule has in creating the membrane structure

4. Cell Membranes
Maintain an internal environment that is different from the external environment.
Regulates what molecules enter and exit the cell.
Membranes are composed of a phospholipid bilayer.

5. Phospholipid Bilayer Lets break down the word.
Phospho- phosphate group
Lipid- fat
Bilayer- 2 layers

6. Phospholipid Bilayer
The phospholipid bilayer is said to be a “Fluid Mosaic Model”.
