Q1. An exoskeleton of an arthropod is chemically treated to identify its carbohydrate component. The results show a nitrogen-containing polysaccharide. This molecule is:
Answer: Chitin
Explanation: Chitin is a structural polysaccharide containing nitrogenous groups, unlike cellulose which is a pure hydrocarbon-based polymer. Glycogen is a storage polymer.
