Lecture 2: Science of Enzymes Lesson 2 1. Enzymes defined Are protein catalysts that accelerate specific chemical reactions.  As catalysts, enzymes: speed  reactions, participate in reactions but are not consumed or changed, and are highly specific. Enzymes are not changed when they perform their function. Can be reused.   Shape of enzyme determines it functionality.   They can be denatured by high temperatures or  extreme pH values. 2. Enzymes as catalysts Lower amount of energy for reaction to proceed to product.  Motorskooter is like a  catalyst.   3. Enzymes as proteins Shape is key to function.  The active site lends specificity to the reaction.  Heat or chemicals can  denature enzymes.  Denaturation changes the protein’s shape and it loses its enzyme activity.  All enzymes are proteins, not vice versa.   4. How to recognize an enzyme Amylase : breaks down amylase/starch
