Lesson 1: Fluid Mosaic Model

Question 1

Cell Membrabes

Answer 1

-called the phospholipid bilayer
- has a characteristics tri-laminar appearance
-7.5nm wide
-composed of phospholipids, proteins, cholesterol, glycolipids and glycoproteins

Question 2

Components of a Membrane

Answer 2

-Glycoprotein
-Glycolipid
-Cholesterol
-Phospholipid Bilayer
-Extrinsic Protein
-Intrinsic Protein
-Channel Preotein

Question 3

The Fluid Mosaic Model

Answer 3

-Fluid/ the phospholipids and proteins are always moving
-Mosaic/ pattern of proteins scattered in amongst the phospholipids

Question 4

Phospholipids

Answer 4

-Head/ hydrophilic and is polar
-Tail/ hydrophobic and non-polar
