Across
  1. 6. A large molecule, or macromolecule, made of many monomers bonded together
  2. 7. Both the reactants and products are made at the same rate in both directions resulting in both reactant and product concentrations staying the same
  3. 9. A chemical reaction that releases more energy than it absorbs; the excess energy is often given off as heat or light
  4. 10. energy the amount of energy that needs to be absorbed for a chemical reaction to start
  5. 13. acids Polymers that are made up of monomers called nucleotides (composed of a sugar, ab phospate group, and a nitrogen-containing molecule called a base
  6. 15. molecules composed of carbon, hydrogen, and oxygen; they include sugars and starches
Down
  1. 1. Small molecules which are subunits of an entire, larger molecule
  2. 2. A polymer made of monomers called amino acids
  3. 3. reaction The change of substances into different substances by breaking and forming chemical bonds
  4. 4. acids Molecules that contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur; 20 different types
  5. 5. A chemical reaction that absorbs more energy than it releases
  6. 8. The substances made by a chemical reaction
  7. 11. energy The amount of energy that will break a bond between two atoms
  8. 12. non-polar molecule that includes fats, oils, and cholesterol
  9. 14. acids chains of carbon atoms bonded to hydrogen atoms; lipids contain fatty acid chains
  10. 16. The substances changed during a chemical reaction
