Note: Respond To All Questions From Part A To C

Fresh pineapple (as well as some other fruits like kiwi and papaya) cells produ enzyme called bromelain that digests gelatin. An enzyme's function i dimensional structure of the molecule. This structure can be alter th se its normal tunction Change in pH can have a significant impact on enzyme activity. How does this influence the ability of an enzyme to function normally? A. B. Every enzyme has a pH optimum as well as a pH range. Think of enzvme that might work well at an acidic pH Think of enzymes that might work well at a neutral pH

Explanation / Answer

A) Changes in pH can make and break intra- and intermolecular bonds, changing the shape of the enzyme and, therefore, its effectiveness.

B) Enzymes in the stomach work well at an acidic pH. The stomach produces hydrochloric acid, and enzymes work well in presence of HCL. Example: pepsin

C) Small intestine has a fairly neutral pH. Chymotrypsin works well at that condition, and it breaks down proteins.
