Enzymes are an example of

• Lipids

• Carbohydrate

• Protein

• Nucleic Acid

Each enzyme only has 1 type of substrate that will fit its active site.  What is this called?

• reusable
• catalyst
• specific
• fragile

What would happen to the reaction rate if you removed an enzyme from a reaction

• It would speed up more

• It would slow down

• The reaction rate would not be affected

Which of these is NOT true?

• Enzymes can denature (change shape) when the temperature gets too high.
• Enzymes can only be used once in a chemical reaction. 
• Extreme pH can denature enzymes.
• Enzymes speed up chemical reactions.
