Plasma Membrane
Functions:
Physical barrier
Separates inside from out
Isolates
Regulate transport/exchange
Controls what enters and leaves
Communication
With other cells and environment
Phospholipids
Phospholipids are arranged in a bi-layer, separating the water outside from the water
inside the cell
Fluid Mosaic Model
Types of Lipids:
1. Phospholipid
Most abundant, semi-fluid
Creates barrier/isolation
2. Glycolipid
Phospholipid with a carbohydrate attached
Communication and recognition
3. Cholesterol
Reinforces/Solidifies structure
