Verified step by step guidance1
Understand the context: The question is asking about a polysaccharide that is crucial for the structure of lobsters and insects.
Identify the function: Polysaccharides are long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds. They serve various functions, including structural support.
Consider the options: The options provided are Chitin, Cellulose, Starch, Glycogen, and Polypeptides. Note that polypeptides are not polysaccharides, so they can be eliminated.
Recall the specific roles: Chitin is known for providing structural support in the exoskeletons of arthropods, such as lobsters and insects. Cellulose is a structural component in plants, starch is a storage form of glucose in plants, and glycogen is a storage form of glucose in animals.
Conclude based on function: Given the structural role of chitin in arthropods, it is the polysaccharide that fits the description in the question.
