Amihipathic - -a hydrophilic and of transport proteins that are present in
hydrophobic region; phosholipid is this membrane and bilayer, being permeable to
primarly small, nonpolar molecules
Fluid mosaic model - -How phospholipids
and proteins are arranged in the membrane of oligosaccharides - -Cell to cell regocnition
cells; membrane is a fluid structure with a mosaic depends on
of various proteins embedded or attached to a
bilayer of phospholipids
