Across
- 4. a chemical reaction in which heat is released to the surroundings
- 5. a type of protein that speeds up metabolic reactions in plants and animals without being permanently changed or destroyed
- 6. a substance that changes the rate of a chemical reaction without being consumed or changed significantly
- 11. a reaction in which one element or radical takes the place of another element or radical in a compound
- 15. a part, substance,or element that lies beneath and supports another part, substance, or element; the reactant in reactions catalyzed by enzymes

Down
- 1. the energy released when a chemical compound reacts to produce new compounds
- 2. a reaction in which two or more substances combine to form a new compound
- 3. a state of balance in which the rate of a forward reaction equals the rate of the reverse reaction and the concentrations of products and reactants remain unchanged
- 7. the oxidation reaction of an organic compound, in which heat is released
- 8. any chemical change in which one species is oxidized (loses electrons) and another species is reduced (gains electrons) also called redox reaction
- 9. a chemical reaction that requires heat
- 10. a reaction in which a single compound breaks down to form two or more simpler substances
- 12. the process in which an electric current is used to produce a chemical reaction, such as the decomposition of water
