Describe the fluid mosaic model of membrane structure. What experimental methods support this model? With regard to membrane fluidity, how can molecules move within membranes? How CAN’T they move? What types of molecules increase or decrease membrane fluidity? How do alpha-helices allow proteins to pass through membranes? Describe the differences between integral membrane proteins, peripheral membrane proteins and lipid-anchored proteins with regard to how they interact with the membrane.

A cell membrane consists of a lipid bilayer, which is a double layer of phospholipids. Each phospholipid has a hydrophilic phosphate head and a hydrophobic lipid tail. These phospholipids are not chemically bound to one another, but rather maintain their structure due to the fact that the lipid tails do not like water. They're hydrophobic^2. If they all buddy up, then they can all stay dry. (See figure.) One way to deal with this quantitatively is to realize that there...
