Question 11
A substance that could be formed as a product, when a polysaccharide undergoes enzyme catalysed hydrolysis, is: A. H₂O B. CO₂ C. C₆H₁₂O₆ D. CH₃OH.CHOH.CH₂OH
Worked Solution & Example Answer:A substance that could be formed as a product, when a polysaccharide undergoes enzyme catalysed hydrolysis, is: A - VCE - SSCE Chemistry - Question 11 - 2002 - Paper 1
Step 1
Identify the product of polysaccharide hydrolysis
Answer
When a polysaccharide undergoes enzyme-catalyzed hydrolysis, it is broken down into simpler sugar units or monosaccharides. For example, starch can be hydrolyzed to glucose.
Evaluating the options:
- A. H₂O: Water is not a product of hydrolysis; it's a reactant.
- B. CO₂: Carbon dioxide is not produced during the hydrolysis of polysaccharides.
- C. C₆H₁₂O₆: This compound is glucose, which is a monosaccharide resulting from the hydrolysis of polysaccharides like starch.
- D. CH₃OH.CHOH.CH₂OH: This represents a type of alcohol and does not directly relate as a product of polysaccharide hydrolysis.
Therefore, the correct answer is B. CO₂.
