Check Your Understanding 1.1 When canned pineapple juice is added to gelatin, it solidifies. This is not the case when fresh pineapple juice is added to gelatin. Explain why. 1.2 , the enzyme occurring naturally in pineapples, is considered a which breaks down proteins into their amino acids by hydrolysis. 1.3 Explain how extremes of temperature and pH alter the activity of an enzyme.

1 When canned pineapple juice is added to gelatin, it solidifies because the canning process involves heating the juice, which inactivates the enzymes present in the pineapple. In contrast, when fresh pineapple juice is added to gelatin, it does not solidify Show more…

Fresh pineapple contains the enzyme bromelain that hydrolyzes peptide bonds in proteins. a. The directions for a gelatin dessert say not to add fresh pineapple. However, canned pineapple where pineapple is heated to high temperatures can be added. Why? b. Fresh pineapple is used in a marinade to tenderize tough meat. Why? c. What structural level of a protein does the bromelain enzyme destroy?

Fresh pineapple contains the enzyme bromelain that has protease activity. Fresh pineapple can be used as a marinade to tenderize tough meat. However, canned pineapple that has been heated cannot. Why? What would you predict would be the optimum temperature for a lactase, a digestive enzyme that functions inside the human intestine?
Qudsiya A.
Commercial meat tenderizers contain papain (extracted from papaya) and/or bromeliad (extracted from pineapple), both of which are enzymes. Because these enzymes "tenderize" meat, what group of organic compounds that you studied in exercise 6 (Carbohydrates, proteins, lipids, and nucleic acids) do you suspect that these enzymes react with? How could you test your answer?
