Question

Quizplus · Accepted Answer

The exoskeleton of insects is mainly composed of chitin, a complex polysaccharide made of N-acetylglucosamine. Chitin provides strength and support to the exoskeleton, allowing insects to move and protect their internal organs. While cellulose is also a carbohydrate, it is not found in the exoskeleton of insects. Dextran is a glucose polymer found in bacteria and sclerotin is a type of protein found in the cuticle of some insects but is not a carbohydrate.
