Integral proteins are directly incorporated with in the lipid bilayer providing channels for water soluble particles. ,[object Object],[object Object],[object Object],[object Object]

2. Lipid all the lipids of the membrane form a lipid bilayer composed of a) Phospholipid & b) cholesterol. ,[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],b) Cholesterol It breakup the close packing of Phospholipid long chain & this disruption make the membrane more fluid.

Cell controls the fluidity of the membrane through the amount of cholesterol. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
