You are doing research in a lab that studies the effect of changing membrane composition on cellular signal transduction. In particular, you are studying the distribution of an important integral membrane protein in the plasma membrane. This protein functions as a receptor for a neurotransmitter. You discover that this receptor is clustered in âpatchesâ in the membrane. This can be explained by (choose all that apply):
| | A) | The receptor interacts covalently with itself and with membrane lipids. | |
| | B) | The receptor diffuses in the membrane in a directed fashion in an attempt to find more of its own âtypeâ so that it can function more efficiently. | |
| | C) | The receptor diffused into a region of the membrane whose lipids have a high percentage of short, unsaturated fatty acid tails. | |
| | D) | The receptor diffused into a region of the membrane whose lipids have a high percentage of long, saturated fatty acid tails. | |
| | E) | The receptor diffused into a region of the membrane that is highly enriched in cholesterol. | |
| | F) | The receptor diffused into a region of the membrane lacking cholesterol. | |
