1- Describe the structures of the 3 types of lipids.
2- Define & Describe the structures of a liposome,a micelle, & a phospholipid bilayer.
3- How do ions cross the lipid bilayer of the cell membrane?
4-What are 6 ways substances are transported into a cell?
5- Why can osmosis only occur if solutions are separated by a selectively permeable membrane?
6-Why do phospholipids organize into a bilayer in an aqueous solution?
7- What part of a lipid molecule is in the middle of a lipid bilayer?
8-Why is the sodium potassium pump called an electrogenic pump?
9-Why is it that when biomedical researchers design drugs that have to enter cells to be effective, they sometimes add methyl (CH3) groups to make the drug molecules more likely to pass through plasma membranes & enter cells?When researchers design drugs that act on the outside of the plasma membranes,sometimes charged groups are added to decrease the chances of the drugs passing through the membranes & entering cells?
