Which carbohydrate is known for providing structure in shells of insects and lobsters?

Cellulose
Chitin
Chitosan
Chlorophyll

The correct answer is: Chitin

Chitin is a carbohydrate that is found in the shells of insects and lobsters. It is a strong structural component that gives the shells their toughness and durability. Cellulose, on the other hand, is found in plant cell walls and does not have the same role in providing structure in animal shells. Chitosan is chemically similar to chitin, but it is found primarily in the cell walls of fungi and other microorganisms. Chlorophyll is a green pigment found in plants that is responsible for capturing sunlight and aiding in photosynthesis. It has no connection to providing structure in insect and lobster shells. Therefore, the correct and only answer for this question is B Chitin.
