  1. a.      membrane can have hundreds of different proteins
                                                                  i.      each membrane protein has defined __relative to the __, so the properties on one surface differ from the other
    1.      called membrane “__”
    • orientation 
    • cytoplasm
    • sidedness
  2. three types
    • integral
    • peripheral
    • lipid-anchored proteins
  3.                                                               i.      integral: __(pass entirely through bilayer and have domains that protrude from __ of the membrane)
    1.      some only have one __ segment, whereas others are __
    • transmembrane 
    • both extracellular and cytoplasmic sides
    • membrane-spanning
    • multispanning
  4.                                                               i.      peripheral: entirely __

    1.      associated with the surface of the membrane by __ bonds
    • outside the lipid bilayer, on either side
    • noncovalent
  5.                                                               i.      lipid-anchored proteins
    1.      located outside __, on either the __ or __ surface, but are __linked to a __molecule that is situated within the __
    • lipid bilayer
    • extracellular or cytoplasmic
    • covalently 
    • lipid 
    • bilayer
