  10. Question #5 Label: 1. Catalyzed rxn 2. Uncatalyzedrxn 3. Substrates 4. Products 5. Activation energy with catalyst 6. A.E. without catalyst

  11. Question #6 • On Friday, we watched as our classmates ate 3 crackers at once. Why did that group of students finish the crackers first as opposed to the group that ate their crackers one at a time? Extra point if you can name the enzyme in our mouth.
