Unit 3 Test #1 Review

Enzymes are made 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

Where do substrates bind on an enzyme?

• voltage-gated channels
• surface receptor
• calcium channels
• active site

What happens when enzymes are heated to a high temperature?

• The enzymes die.
• The shapes of the enzyme are altered or denatured
• The enzymes' amino acid sequence changes.
• The enzymes remain the same

What happens to an enzyme when it is denatured?

• Activation energy is lowered.
• It becomes stronger.
• It loses its shape.
• Activation energy is raised.
