Concept #1: Peripheral Membrane Proteins

Practice: Peripheral membrane proteins: 

a) Penetrate deeply into the lipid bilayer. 

b) Can only be released from membranes by disrupting membrane structure via treatment with detergents. 

c) Are non-covalently bound to membrane lipids or integral proteins. 

d) Consist of β-barrels forming a hollow cylinder that creates a pore within the membrane. 

e) Are covalently attached to carbohydrates that span the bilayer.

Practice: Label each of the following as a characteristic of (A) Integral and/or (B) Peripheral Membrane Proteins: 

a) Could function on either side of the membrane: ___________. 

b) Can act as a tunnel through the cell membrane: ___________. 

c) Attaches only at the surface of a cell’s membrane: ___________. 

d) Extends through all or part of the membrane: ___________. 

e) Loosely associated with the membrane: ___________. 

f) Can act as amphitropic proteins: ___________.
