AP Bio Unit 3: Enzymes

Enzymes are an example of

• Lipids

• Carbohydrate

• Protein

• Nucleic Acid

What is the purpose  of an enzyme?

• give permission for the reaction
• raise activation energy
• speed up reactions
• control how many reactions occur

Letter D...

• active site
• enzyme
• substrate
• products

Letter B...

• active site
• enzyme
• substrate
• products

Letter C...

• active site
• enzymes
• substrate
• products

An enzyme speeds up a reaction by

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