Guida verificata passo dopo passo1
Understand the role of polysaccharides in biological systems: Polysaccharides are long chains of monosaccharide units and serve various functions such as energy storage and structural support.
Identify the function of each polysaccharide listed: Chitin is a structural polysaccharide found in the exoskeletons of arthropods, Starch is a storage polysaccharide in plants, Glycogen is a storage polysaccharide in animals, and Cellulose is a structural polysaccharide in plant cell walls.
Focus on the context of the question: The question asks for the polysaccharide stored as an energy source in animals.
Recall the specific function of Glycogen: Glycogen is the primary storage form of glucose in animals, stored mainly in the liver and muscle tissues, and is used as a quick energy source when needed.
Conclude that Glycogen is the correct answer based on its role as an energy storage polysaccharide in animals.
