Verified step by step guidance
1
Understand the role of polysaccharides in biological systems. Polysaccharides are long chains of monosaccharides linked by glycosidic bonds, and they serve various functions such as energy storage and structural support.
Identify the function of each polysaccharide listed in the options. Glycogen, chitin, cellulose, and starch each have distinct roles in organisms.
Glycogen is primarily used for energy storage in animal cells. It is a highly branched polysaccharide composed of glucose units, allowing for rapid release of glucose when energy is needed.
Chitin is a structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi, not primarily used for energy storage.
Cellulose is a structural polysaccharide found in the cell walls of plants, providing rigidity and strength, while starch is used for energy storage in plants, not animals.
