We used different types of pineapple as sources of the enzyme bromelain and looked at whether it can affect the setting of gelatin. Why is it possible to make Jell-O with canned pineapple chunks but not with fresh pineapple chunks? Select one: a. All the answers are correct. b. The fresh pineapple chunks still have live enzymes that will prevent the Jell-O from setting. c. Canned pineapple chunks are heated during the canning process; therefore, there are no active enzymes in the canned pineapple. d. None of the answers are correct.

Enzymes can perform hydrolysis on their substrate or they can perform dehydration. Bromelain is an enzyme that is found in pineapple or papaya. This enzyme breakdown the peptide bond of proteins. So does this enzyme perform hydrolysis or dehydration?

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.
