Answer Key to Handout for Week 8: Lipids: 1. It is going to form a lipid bilayer with edges exposed initially. The hydrophobic tails are going to face the middle of the bilayer while the hydrophilic heads are going to face the outside of the bilayer interacting with the polar solvent. 2. This will form a micelle because the heads are larger so it will cause the lipid layer to curve and form a sphere with the heads facing outside and the tails facing inside. The heads interact with polar solvent. 3. A lipid bilayer is likely to form a vesicle because of the exposed hydrophobic edges. This vesicle can be used to transport substances into and out of the cell through exocytosis and endocytosis. The center of the vesicle will have hydrophilic heads and the outside of the vesicle will have hydrophilic heads also since it is a bilayer and not a single layer like a micelle. 4. If lipids normally found inside the cell are suddenly found on the outside, then this is a signal to macrophages and other immune cells that there is something wrong with the cell. This will cause the cell to be destroyed. 5. The charge inside the cell is negative with comparison to the outside of the cell. This charge is due to the activity of the Na+K+atpase transport protein.
