BIO 320 Lecture Notes - Lecture 5: Clathrin, Cell Membrane, Caveolin
Document Summary
Access code: 1988; if you ever get locked out, call 471-2020. Make a list/discuss of the ways by which proteins are aggregated for secretion. (5: protein pump signal patches on certain proteins, not clathrin that does selective aggregation! (5) Make a table of the different methods of endocytosis. (10-14) Pinocytosis (clathrin) virtually all eukaryotic cells clathrin coated pinocytic vesicles; dynamin. Utilizing your knowledge of the clathrin-coat complex, discuss how atherosclerosis develops. In other words, how do we develop high concentrations of ldl in our blood? (16,17) Generalize the process of phagocytosis into 3 basic steps. (23: use the board for this one. Compare and contrast the four major ways a cell can partake in signaling. Discuss the two ways in which a ligand can bind its receptor. What must happen if a receptor initially resides in the cytoplasm? (4, 5) Using acetylcholine as an example, explain the two methods by which one ligand can induce different signals. (8)
