Experiment: Fruit juice was treated with different enzymes (pectinase, cellulase, amylase). Juice clarity was observed.Observation: Pectinase-treated juice was clearer than others.Question: What is the likely reason?
Correct answer: D. Pectinase breaks down pectin, improving juice clarity.
- A. Amylase is responsible for breaking down starch into sugars.
- B. Cellulase breaks down cellulose into glucose.
- C. Enzymes have specific functions beyond just reducing pH.
- D. Pectinase breaks down pectin, improving juice clarity.
Explanation
The correct answer is option D. Pectinase breaks down pectin, a substance that can cause cloudiness in fruit juice. By breaking down pectin, pectinase improves juice clarity, which is why the pectinase-treated juice was clearer than the others. Options A and B are incorrect as they attribute unrelated functions to the enzymes mentioned in the experiment. Option C is incorrect as enzymes like pectinase have specific functions beyond just reducing pH levels.
