Question

A complex polysaccharide produced from sucrose by the bacterium Leuconostoc mesenteroides is:

• A. Chitin
• B. Starch
• C. Cellulose
• D. Dextran

Answer 1

The correct option is D Dextran

Dextran is a low molecular weight polymer of glucose. It is produced by the bacterium Leuconostoc mesenteroides by fermentation of sucrose solution.
Chitin is a structural homopolysaccharide that forms the cell wall of fungi and exoskeleton of insects.
Cellulose is also a structural homopolysaccharide that constitutes the cell wall of plant cells.
Starch is a storage homopolysaccharide found in different parts of plants.
