enzyme 9C

How do enzymes speed up chemical reaction?

• Increasing activation energy

• Decreasing activation energy

• Increasing deactivation energy

• Decreasing deactivation energy

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shapes of the enzyme are altered denature

• The enzymes' amino acid sequence changes.

• The enzymes remain the same
