3. You have a protein that is easily extracted from a cell membrane preparation, without any associated lipids, by washing with a buffer containing a salt (e.g. 2M NaBr) without the need to treat the membrane with detergents. What type of protein do you have? E) Peripheral (extrinsic) F) A protein covalently anchored to membrane fatty acids G) Transmembrane H) None of the above Answer: Explanation: 4. A bacterium is suddenly expelled from a warm human intestine into the cold world outside (hey, it's been a cold December!). Which of the following adjustments might the bacterium make to maintain the same level of membrane fluidity? I) Produce lipids with hydrocarbon tails that are longer and have fewer double bonds Produce lipids with hydrocarbon tails that are shorter and have more double bonds K) Decrease the amount of cholesterol in the membrane L)Decrease the amount of glycolipids in the membrane Answer: Explanation: 5. Which of the following membrane lipids does not contain fatty…
