NAME ___________________________________ Bio 311C Worksheet : Cell Membrane Structure & Function 1. Describe the Fluid Mosaic Model of membrane structure. 2. What factors affect membrane fluidity? How do they affect fluidity (increase or decrease?)? 3. Compare integral membrane proteins and peripheral membrane proteins based on structure and location. 4a. What is the main function of membrane glycoproteins and glycolipids? On which side of the plasma membrane are you most likely to find such molecules? 4b.  Outline the events involved in the production & targeting of a membrane glycoprotein.  How does the cell ensure that the sugars  are on the proper side of the membrane? 5a. What does it mean for a substance to “diffuse down its concentration gradient?” 5b. Can a substance diffuse against its concentration gradient? Explain. 5c.
