1. Enzymes

2. Enzymes: Definition
Proteins that bind to a substrate and either make or break bonds
(assist in chemical reactions)

3. Characteristic 1 Catalyze chemical reactions: Speed up Reactions
Decrease the amount of activation energy

4. Characteristic 2 Work on highly specific substrates
Substrate attaches to Active Site and is converted to product

5. Characteristic 3 Can be blocked by chemicals or toxins
This prevents them from working
Called inhibitors

6. Characteristic 4 Can Denature: change shape and stop working due to pH
Temp
Salt

7. Anatomy of an Enzyme
Substrate binds at the active site
