  1. Enzyme Review

  2. What Are Enzymes? Enzymes are Proteins that speed up chemical reactions. They act as Catalysts to break and form bonds when molecules interact End in -ase 2

  3. Enzyme Structure The substance an enzyme acts on is the substrate The active site is the region on an enzyme where the substrate binds. Enzyme 3

  4. Lock and Key Model Enzymes are specific for what they will catalyze Substrate and active site fit together like a lock and key 4

  5. Example: Sucrase (enzyme) sucrose (substrate)

  6. More Examples: • What do you think the following enzymes break down and build back up: • Lipase • Protease • DNA helicase • Lactase • Maltase

  7. What can Denature an Enzyme? high tempsmay denature (unfold) the enzyme. pH (most like 6 - 8 pH near neutral) Ionic concentration (salt ions) 8
