Enzyme Review 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 3 Enzyme Structure 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 4 Lock and Key Model Enzymes are specific for what they will catalyze Substrate and active site fit together like a lock and key Example: Sucrase (enzyme) sucrose (substrate) Sucrase More Examples: What do you think the following enzymes break down and build back up: Lipase Protease DNA helicase Lactase Maltase 8 What can Denature an Enzyme? high temps may denature (unfold) the enzyme. pH (most like pH near neutral) Ionic concentration (salt ions)
