  1. Packet 1 • 1. Atom • 2. A type of atom, a pure substance that consists entirely of one kind of atom, etc. • 3. A substance formed by the chemical combination of two or more elements • 4. Made of 7 total atoms: 2 hydrogen, 1 sulfur, 4 oxygen • 5. Chemical bonds • 6. Low numbers = acidic, high numbers = basic • 7. a, d

  2. Packet 2 • 1. It can bond to other carbon atoms • 2. macromolecules • 3. polymerization • 4. a polymer • 5. Carbohydrates, lipids, nucleic acids, proteins • 6. Carbon, hydrogen, oxygen • 7. a, b, d • 8. monosaccharides • 9. Macromolecules formed from monosaccharides bonded together

  3. 10. Glycogen in animals, starch in plants • 11. Carbon and hydrogen • 12. fatty acids • 13. a, b, d • 14. Carbon, hydrogen, oxygen, nitrogen, phosphorus • 15. Nucleotides • 16. Store and transmit hereditary information • 17. DNA and RNA • 18. Carbon, hydrogen, oxygen, nitrogen • 19. Amino acids • 20. Help carry out chemical reactions, form structures, transport substances, help fight disease.

  4. PACKET 3 • 1. The process of making or breaking chemical bonds to form different compounds. • 2. Reactants = Elements or compounds that enter into a reaction Products = Elements or compounds that are produced by a reaction • 3. Energy • 4. Activation energy • 5. (Leftmost point on the line = energy of reactants, rightmost point on the line = energy of products, arrow = activation energy)

  5. 6. Enzymes • 7. Speed up chemical reactions by lowering their activation energy • 8. Substrates • 9. Because the active site fits perfectly to just one kind of substrate/s • 10. If the environment is too acidic or too basic, it denatures the protein, changing the enzyme’s shape. This prevents the substrate from being able to bind to the active site.
