FAQs on Polysaccharides: Starch, Cellulose & Glycogen Video Lecture - Chemistry Class 12 - NEET

1. What are polysaccharides?
Ans. Polysaccharides are complex carbohydrates composed of long chains of sugar molecules. They are formed by joining multiple monosaccharide units together through glycosidic bonds.
2. What is the role of starch in the body?
Ans. Starch serves as a major energy storage molecule in plants. In the body, it is broken down into glucose to provide energy for various cellular processes and to maintain blood sugar levels.
3. How is cellulose different from starch?
Ans. Cellulose and starch are both polysaccharides, but they have different structures and functions. Cellulose is the main component of plant cell walls and provides structural support, while starch is used for energy storage in plants.
4. What is the function of glycogen in the body?
Ans. Glycogen is the primary storage form of glucose in animals, including humans. It is stored in the liver and muscles and can be broken down into glucose when energy is needed, such as during exercise or fasting.
