D
Sucrose
Verified step by step guidance
1
Understand the definition of a polysaccharide: Polysaccharides are long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds. They are typically used by organisms for energy storage or structural purposes.
Identify the function of each option: Cellulose is a structural polysaccharide found in the cell walls of plants. Chitin is a structural polysaccharide found in the exoskeletons of arthropods and cell walls of fungi. Sucrose is a disaccharide, not a polysaccharide, and is used for energy transport in plants.
Focus on Glycogen: Glycogen is a polysaccharide that serves as a form of energy storage in animals and fungi. It is primarily stored in the liver and muscle tissues.
Compare the energy storage capabilities: Glycogen is highly branched, which allows for rapid release of glucose when energy is needed, making it an efficient energy storage molecule.
Conclude that Glycogen is the correct answer: Based on its structure and function, Glycogen is the polysaccharide that is great at storing energy among the given options.
