For 10 points, name this outermost structure of an animal cell.
The GLUT family of proteins is associated with this structure, and one model of its movement is known as the elastic Brownian ratchet model. In epithelial cells, the GPI anchor sorts proteins into those designated for the apical or basolateral domains of this structure. Singer and Nicholson modeled this structure as a (*) fluid mosaic, and it is composed of a hydrophilic outside and a hydrophobic core, which make up its phospholipid bilayer.
