- 4. A substance that binds to an enzyme and reduces its activity, thus slowing a chemical reaction that the enzyme catalyzes.
- 6. The substances formed during a chemical reaction, usually indicated on the right-hand side of the chemical equation.
- 7. A class of organic compounds that serve as the building blocks for the information storage molecules DNA and RNA.
- 9. A class of organic compounds that serve as the building blocks of proteins.
- 11. A class of simple organic compounds important in living things as a source of both energy and structure.
- 12. A substance that changes the rate of a chemical reaction but is not itself used up or affected by the reaction.
- 14. The attraction of particles in one substance for particles in a different substance.
Down
- 1. A covalently bonded compound containing the element carbon.
- 2. An organic compound comprised of the elements carbon, hydrogen, and oxygen; includes sugars, starch, and cellulose.
- 3. The process by which particles in solution are evenly distributed throughout the solvent by Brownian motion.
- 5. A class of nonpolar organic compounds that are insoluble in water and are used for energy storage and cell membranes in living things.
- 6. Quality of molecules having an uneven distribution of electrical charge, resulting in some regions of a molecule having negative charge while others are positive.
- 8. A naturally occurring catalyst, usually a protein.
- 10. The attraction between like particles within polar substances.
- 13. A substance that is present before a chemical reaction and takes part in it, usually shown on the left-hand side of a chemical equation.
