Regulates what goes in and out of the cell and enables cells to communicate with each other |
|
|
COMPONENTS OF THE PLASMA MEMBRANE |
-Phospholipid Bilayer -Cholesterol -Carbohydrate chains -Proteins Extracellular matrix (ONLY IN ANIMAL CELLS) |
|
|
|
HYDROPHILIC POLAR HEADS (Water loving)
|
Associate with polar water molecules outside and inside the cell |
|
|
|
HYDROPHOBIC NONPOLAR TAILS (Water fearing) |
Associate with each other because they want to "get away" from the polar water |
|
|
|
CHOLESTEROL |
Helps modify the fluidity of the membrane over a range of temperatures |
|
|
|
Phospholipid + carbohydrate chain = |
Glycolipid |
|
|
|
PROTEIN + CARBOHYDRATE CHAIN= |
Glycoproteins In animal cells they give the cell a sugar coat called glycocalyx |
|
|
|
GLYCOCALYX |
Protects the cell and has various functions including cell to cell adhesion, reception of signaling molecules, and cell to cell recognition |
