MCQ on Polysaccharides




Polysaccharides are complex carbohydrates composed of multiple monosaccharide units linked together. Examples include starch, cellulose, and glycogen. They serve as energy storage (like glycogen) and structural components (like cellulose in plant cell walls) in living organisms. This is an MCQ on Polysaccharides Structure, Functions with Examples.
