BIOL 1202 Lecture Notes - Lecture 11: Fluid Mosaic Model, Lipid Bilayer, Cell Membrane
Document Summary
Prokaryotic cells have one membrane, the plasma membrane. Eukaryotes have many, used to separate the various cell compartments. List a key difference that nuclear and mitochondrial membranes shares, that the. What is the membrane"s approx. thickness? others do not. Do internal membranes have the same general structure/composition as the plasma. Same general structure but different combinations, also double vs single membrane? membranes. If you place pure phospholipids in water, ___________ are formed. liposomes. Remember the ecf and cytoplasm are mainly composed of water. A bilayer of lipids forms the backbone of the plasma membrane . The most abundant type of lipid is phospholipids. Other lipids include cholesterol (which can be up to 20% of the lipid weight in a membrane) and glycolipids. The proteins are variable in structure and function and how they are attached to the membrane. There are also oligosaccharides added at various parts in the membrane, so membrane composition includes carbohydrates.
