  1. 3. This organelle is a site of protein synthesis.
  2. 4. ________ is the molecule that the enzyme works on.
  3. 6. This organelle creates turgor pressure in plants. Turgor pressure keeps a plant from "wilting".
  4. 9. What is the site of digestion in animal cells?
  5. 10. ____________ inhibition occurs when an area other than the active site is bound by another molecule. The binding of this molecule changes the shape of the enzyme so that the substrate cannot enter the active site.
  6. 17. __________: A characteristic of living things where there is a constant internal environment.
  7. 18. This is the organelle where cellular respiration occurs.
  8. 19. When an enzyme is _______ it will not work anymore.
  9. 21. What synthesizes and stores starch in plants?
  10. 25. ________ is where substrates bind their specific enzyme.
  11. 27. _________ is an example of a prokaryotic cell.
  12. 29. Enzymes are biological ________. This means that they speed up the chemical reactions in living things.

  1. 1. These are used to build the cytoskeleton and mitotic spindle.
  2. 2. The membrane is composed of a ________ bilayer.
  3. 5. What color are chloroplasts?
  4. 7. ________ are positive regulators of enzymes.
  5. 8. This organelle prepares and stores proteins for secretion in the cell.
  6. 11. What is an organelle that the plant cells have that the animal cells do not have?
  7. 12. __________ cells are simple cells with no nucleus.
  8. 13. ________ are negative regulators of enzymes.
  9. 14. Where the ribosomes are made.
  10. 15. _________ inhibition occurs when the active site is bound to another molecule. When bound, the substrate can no longer enter the active site.
  11. 16. Intra-cellular enzymes are the enzymes found inside our cells. Extracellular enzymes are the enzymes found ________ our cells.
  12. 20. This organelle is used to transport things in the cell.
  13. 22. _________ energy is the amount of energy that needs to be absorbed for a chemical reaction to start.
  14. 23. What is an organelle that the animal cells have that the plant cells do not have?
  15. 24. pH and ______ can denature an enzyme.
  16. 26. This is the genetic material found in the nucleus. It is made of DNA.
  17. 28. ______ is an example of an enzyme that helps to turn starch into a sugar called maltose.
