1. Enzymes- Outline Enzymes and ph Enzyme def Lock and key comparison All enzymes have names that end in Multi-enzymes: vitamin shoppe Catalysts: enzymes

2. Enzymes Catalyst: speeds up a reaction Enzyme def: a protein that speeds up a reaction that takes place in cells. Enzymes/Catalysts are not part of the reaction

3. Enzymes- work best at a certain temp and pH Enzymes are specific, usually only catalyzing specific reactions

4. Lock and key comparison: enzymes provide a place where reactants can come together and complete the reaction. (the reactants in the reaction are called substrates)

6. Multi-enzymes- can be purchased at places like the Vitamin Shoppe Most enzymes have names that end in – “ase”

7. Review… Catalysts speed up the rate of the reaction by lowering the activation energy: Enzymes are biological catalysts
