Across
  1. 3. site A region on an enzyme that binds to a protein or other substance during a reaction.
  2. 6. Inhibition The inhibitor binds to the enzyme's active site and prevents the substrate from binding, stops the reaction from happening
  3. 8. Energy The minimum energy required to allow a certain chemical reaction to occur
  4. 9. The substance on which an enzyme acts
  5. 10. Enzymes An enzyme that is attached to an inert, insoluble substance. Can provide increased resistance to changes in conditions
  6. 13. Complex The intermediate formed when a substrate interacts with the active site of an enzyme
  7. 14. Inhibitor The reaction product inhibits the enzyme activity
  8. 17. Something which prevents an enzyme from working in the normal manner
  9. 21. Inhibitor An enzyme inhibitor which does not prevent the enzyme from functioning properly permanently
  10. 22. Rate of Reaction Instantaneous rate of reaction at the start and first few seconds of the reaction
  11. 23. Fit Hypothesis The binding of a substrate or some other molecule to an enzyme causes a change in the shape of the enzyme so as to enhance or inhibit its activity
Down
  1. 1. The maximum rate of reaction when the enzyme is saturated with substrate
  2. 2. To prevent an enzyme from working in the normal manner
  3. 4. Protein molecules that act as biological catalysts
  4. 5. Inhibition The inhibitor can bind to the enzyme without preventing the substrate from binding, lowers the enzyme's efficiency
  5. 7. Operating within the cell
  6. 11. Mechanism A process that uses the conditions of one component to regulate the function of the other. It is done to either increase or dampen the change in the system.
  7. 12. Catalysts A molecule which speeds up a chemical reaction
  8. 13. Operating outside of the cell
  9. 15. What is left after the enzyme binds with the substrate
  10. 16. A measure of how acidic or basic something is on a scale of 1-14 with 1 being most acidic, 7 being neutral, and 14 being most basic
  11. 18. pH The pH level at which a specific enzyme can work most effectively
  12. 19. Rate The number of chemical conversions of the substrate molecules per second at a catalytic site for a given enzyme concentration
  13. 20. To alter the structure of a protein by breaking bonds
