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