Fluid mosaic model B4

Question 1

What does the fluid mosaic model consist of?

Answer 1

-Proteins, Glycoproteins, Phospholipds and carbohydrates

Question 2

Why is it called the fluid mosaic model?

Answer 2

-The phospholipid molecules form a bilayer that are constantly moving around relative to one another, giving it a fluid structure
-The protein molecules are unevenly distributed throughout the membrane forming a mosaic
-The agreed structure is based on experimental evidence so it’s a model

Question 3

What are intrinsic proteins?

Answer 3

The membrane proteins which are embedded completely or partly through the lipid bilayer of the membrane

Question 4

What are extrinsic proteins?

Answer 4

Loosely bound proteins located outside the membrane
