The polysaccharide that contains nitrogen is
Correct answer: A. Chitin
- A. Chitin
- B. Starch
- C. Cellulose
- D. Glycogen
Explanation
Chitin is the correct answer because it is a polysaccharide that contains nitrogen, specifically in its N-acetylglucosamine monomers. This makes it structurally distinct from other common polysaccharides like starch, cellulose, and glycogen, which are composed solely of glucose units and do not contain nitrogen. Chitin is found in the exoskeletons of arthropods and is a key component in the cell walls of fungi.
