Polysaccharides: the large carbohydrates you want to meet

The video explores the connection between life and energy, emphasizing the role of polysaccharides. It introduces polysaccharides, explaining their types and functions, focusing on glycogen, starch, and cellulose. Glycogen is highlighted as a key energy storage molecule in humans, while starch serves a similar role in plants. Cellulose is discussed for its structural importance in plant cell walls. The video concludes with a humorous note on cellulose's role in digestion and paper production.
