BIOL 120 Lecture Notes - Lecture 10: Lipid Raft, Patch Clamp, Electric Potential
Document Summary
Bmsc 220. 3 cell biology. Topic 10: plasma membrane and cell surface. Topic overview: plasma membrane organization and fluid mosaic model, membrane transport, passive diffusion, facilitated diffusion, active transport, endocytosis. Learning objectives: describe the basic structure of the plasma membrane in terms of: Textbook readings (5th edition: chapter 13, pages 529- 546, 551- 566. However, the mobility of some proteins is restricted by their associations with other proteins or specific lipids. Ion gradients are frequently used as a source of energy to drive the active transport of other molecules. Endocytosis: phagocytosis, cells ingest large particles, such as bacteria and cell debris, by phagocytosis. The plasma membrane of mammalian red blood cells: mammalian red blood cells are used as a simple experimental system. They associate with the outer surface of the membrane but are not in any way embedded. Integral membrane proteins can be released only by experimental treatments, such as amphipathic detergents, that disrupt the phospholipid bilayer.
