Across
  1. 5. The part of the enzyme’s active site where the chemical reaction actually happens.
  2. 7. The idea that each enzyme only catalyzes one type of chemical reaction.Competitive
  3. 10. Inhibition where the inhibitor binds to another site on the enzyme and reduces its activity.
  4. 12. A change in the shape of an enzyme (usually caused by heat or pH) that makes it stop working properly.
  5. 14. The idea that each enzyme can only bind to a particular substrate.
  6. 16. Site on an enzyme where a regulator binds, away from the active site.
  7. 17. All the chemical reactions that happen in the cells of a living organism to keep it alive and functioning.
Down
  1. 1. The part of the enzyme’s active site where the substrate attaches.
  2. 2. A substance formed as a result of a chemical reaction.
  3. 3. The substance that an enzyme acts on during a chemical reaction.
  4. 4. A protein that speeds up (catalyzes) a chemical reaction in the body without being used up.
  5. 6. A starting substance in a chemical reaction.
  6. 8. A process where substances (reactants) are changed into new substances (products).
  7. 9. The specific part of the enzyme where the substrate binds and the reaction takes place.
  8. 11. Inhibition where the inhibitor competes with the substrate for the enzyme’s active site.
  9. 13. A substance that speeds up a chemical reaction without being changed itself — enzymes are biological catalysts.
  10. 15. Inhibition where the final product of a pathway stops an earlier reaction.
