(i.e. where is lactose broken down) 6. What do you propose would be the optimal temperature for lactase activity and why? 7. What do you propose would be the optimal pH for lactase activity and why? 8. How does the chemical structure of lactose compare to maltose? 9. Do you think the lactase enzyme will be able to hydrolyze (split apart) the maltose molecule in addition to the lactose molecule? Why or why not? 10. What was your hypothesis concerning the cofactor experiment? What was the purpose of the EDTA? Did addition of EDTA reduce the enzyme activity?
