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