12. What happens to the activity of sucrase as the pH becomes more alkaline? Section 5 - short answer (5 pts)During chemistry lab, Maria places sucrose in a glass beaker, adds water, and stirs. As the table sugar disappears, she loudly proclaims that she has chemically broken down the sucrose into fructose and glucose. Is Maria's chemical analysis correct? Why or why not?
