BIOLOGY 235 MIDTERM 1- VERSION B 1. Know components of the lipid bi-layer o The basic structural framework of the plasma membrane is the lipid bilayer, two back-to-back layers made up of three types of lipid molecules—phospholipids, cholesterol, and glycolipids o The bilayer arrangement occurs because the lipids are amphipathic molecules, which means that they have both polar and nonpolar parts. 2. Bonds between water molecules- what type of bond is it? o Polar covalent/hydrogen bond ...
