How do enzymes affect activation energy?

• Require a higher activation energy

• Allow for a lower activation energy (Speed up the chemical reaction)

• It does not change the activation energy

Looking at the red line, what observation can you make about the activation energy needed when an enzyme is not present?

• The activation energy needed is higher without the enzyme.
• The activation energy is lower without the enzyme.
• The activation energy remains the same with or without the enzyme.
• The activation energy is only affected by temperature, not by the presence of an enzyme.
