Lesson 2 1. Enzymes defined- protein catalysts that accelerate specific chemical reactions.   Enzymes as catalysts:  -speed reactions -participate in reactions but are not consumed or changed -are highly specific (have an active site) Notes about animation: -each enzyme has only one reaction that it can help with. -enzymes are not changed when they perform their function, so they can be used repeatedly  -the shape of an enzyme is what determines its function -Enzymes are affected by high temps or extreme pHs - this can lead to denaturing and makes the enzyme less effective or even  useless 2. Enzymes as catalysts- lower the energy of the reaction.   3. Enzymes as proteins-shape is key to function - active site is specific for a certain substrate.   - Heat and chemicals can denature the protein and change shape of the active site.   4. How to recognize an enzyme- look at name. -
