1. You body contains 2 x 1025 molecules, most of which can be classified as being a part of one of the four fundamental biological molecule classes. (a) Please state all four of these fundamental biological classes, being sure to provide both the name of the building blocks as well as the name of the macromolecules. (b) For each of the above listed fundamental biological macromolecule classes, please provide at least 3 important role that that molecule class plays in a living system. Biological Macromolecule Function 1 Function 2 Function 3 2. Please fill in the blank below with the name of the force that this description matches: i. I'm an extremely weak force, but I am present in all molecules: LDF ii. I'm responsible for holding biological molecules like DNA and proteins in the proper shapes iii. I'm the strongest for we've talked about: iv. I'm the force that occurs because I can't do almost any other intermolecular force: v. I'm the force that occurs between metals and nonmetals: vi. I'm the force that occurs between water molecules and salt that is dissolved in that water molecule: vii. I am the force that allows the lipid bilayer to form spontaneously
