Question 4
4.
What is an enzyme's function?
A. stores genetic information
B. speeds up chemical reactions
C. provides structure
D. provides energy
Question 5
5.
Do chemical reactions occur without enzymes present?
A. No the reaction cannot occur at all
B. Yes the reaction happens but the reaction is slower
Question 6
6.
How do enzymes affect the activation energy (energy needed to start a reaction)
A. lower the activation energy so the reaction happens faster
B. increases the activation energy so the reaction does not occur
C. Does not change the activation energy

Question 9
9.
When heat is added to an enzyme, it denatures. What does denature mean?
A. the enzyme works faster
B. The enzyme loses it shape and cannot function
