1 Cell Membrane Structure

2 Cell Membrane (aka. Plasma membrane)
semi-permeable fluid portion is a double layer of phospholipids, called the phospholipid bilayer

3 Phospholipid bilayer Phospholipids contain a polar hydrophilic (likes water) head hydrophobic (hates water) tail and a non-polar

4 Proteins embedded in membrane serve different functions
regulate movement of substance form small openings for molecules to diffuse through Transport Proteins Channel Proteins

5 Receptor Proteins Recognize and binds to substances outside the cell.

6 Cell-Surface Markers Made of carbohydrates used to identify cell types.

7 Jobs of the cell membrane:
Separate the internal from external Regulate the exchange of substances Communicate with other cells Identification
