Diagram and describe the structure of the plasma membranes of animal cells. How is membrane structure related to permeability? Explain the various ways that different substances cross cell membranes. Give an example of something that crosses membranes each way, and explain why this substance must cross membranes by that particular route, and not some other way. [Hint: Your answer should include all the things that are attached to the membrane, the interactions that hold membranes together, what controls membrane fluidity,...

SDS-PAGE is often used to determine the location and orientation of membrane associated proteins. Commonly, experimental preparations of membranes are treated in a variety of ways in order to extract the proteins, which are then subjected to SDS-PAGE. These treatments will affect membrane proteins in different ways, based on how they are arranged in the membrane. One of the most common pre-treatments is by the digestive enzyme trypsin, which degrades polypeptide chains. Trypsin is too large to cross a membrane,...

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.
