  1. 1. A non-protein helper that assists enzyme function, often derived from vitamins.
  2. 2. A biological catalyst that speeds up chemical reactions.
  3. 3. The process where an enzyme loses its shape and function, often due to heat or pH changes.
  4. 4. Type of inhibitor that binds elsewhere on the enzyme, altering its function.
  5. 6. The sum of all chemical reactions occurring within a living organism.
  6. 7. The molecule upon which an enzyme acts.
  7. 9. A molecule that decreases the activity of an enzyme.
  8. 12. Type of reaction where small molecules are built into larger ones.
  9. 13. energy The energy needed to start a chemical reaction, lowered by enzymes.
  10. 14. An environmental factor that can increase enzyme reaction rates up to an optimum.
  11. 16. fit Model describing how enzymes change shape slightly to fit the substrate.
  12. 19. Type of reaction where large molecules are broken down into smaller ones.
