Biochemistry Study Guide (Part 4)- Enzymes

Enzymes are an example of

• Lipids

• Carbohydrate

• Protein

• Nucleic Acid

What is the function of an enzyme?

• enzymes break themselves into small pieces
• enzymes slow down chemical reactions
• enzymes speed up chemical reactions
• enzymes combine products to form reactants 

What is a substance called if it speeds up a chemical reaction?

• reusable
• catalyst
• specific
• fragile

An enzyme speeds up a reaction by

• lowering the activation energy.
• raising the activation energy.
• releasing energy.
• absorbing energy.

With what 3 letters do enzymes typically end?

• -ose
• -ase
• -ese
• -tic

In the diagram, what is letter A?
