  3. 7. goes along with the lock, in enzymes
  4. 8. goes along with the key, in enzymes
  5. 11. the part of an enzyme where the reaction occurs
  6. 13. more of these ions lower the pH
  7. 14. a reactant in an enzyme-catalysed reaction
  8. 15. a poison that affects an enzyme in respiration
  9. 16. enzyme that breaks down harmful ions in liver cells
  10. 17. a molecule that can speed up an enzyme-catalysed reaction

  4. 6. starch-digesting enzyme
  5. 9. a compound that reduces the activity of an enzyme
  6. 10. a protein-digesting enzyme
  7. 12. this factor affects an enzyme's activity
  8. 15. a molecule that speeds up a reaction but is not affected itself
