2. WHAT IS AN ENZYME? Biological catalyst or assistants to carry out chemical reactions Consist of Various types of proteins

3. DIFFERENCE BETWEEN OTHER PROTEINS AND ENZYMES? Enzymes speed reactions by lower activation energy while other “proteins” do not. ENZYMES usually end in -ASE

4. CATALYST IS AN… Assistant

5. CATALYST REACTANTS Chemicals transformed without the help of an enzyme (no push) SUBSTRATE Chemical that are transformed to help the enzyme

6. 4 THINGS THAT CHANGE ENZYMES Temperature pH Substrate Energy
