The best example of of polysaccharide which is stored in animaIs is called:
Correct answer: D. Glycogen
- A. Lactose
- B. Cellulose
- C. Glucose
- D. Glycogen
Explanation
Lactose: Lactose is a disaccharide composed of one molecule of glucose and one molecule of galactose. It is commonly found in milk and dairy products. Lactose serves as an energy source for young mammals, including human infants. However, it is not the best example of a polysaccharide stored in animals. Cellulose: Cellulose is a polysaccharide and an important structural component of plant cell walls. It provides rigidity and strength to plant cells and is the most abundant organic compound on Earth. While cellulose is a polysaccharide, it is not stored in animals. Animals lack the enzymes necessary to digest cellulose effectively. Glucose: Glucose is a monosaccharide, not a polysaccharide. It is a simple sugar and serves as a primary source of energy for living organisms. Glucose is transported through the bloodstream and used by cells for energy production. It is not stored as a complex polysaccharide in animals. Glycogen: The correct option is glycogen. Glycogen is a highly branched polysaccharide composed of glucose units and serves as the primary energy storage molecule in animals, including humans. It is the animal equivalent of starch in plants. Glycogen is stored in the liver and muscles, where it acts as a readily available source of glucose during periods of increased energy demand. When energy is needed, glycogen is broken down into glucose units, which are further utilized through cellular respiration to produce energy.In summary, option d) Glycogen is the correct option. Glycogen is the best example of a polysaccharide stored in animals. It serves as an important energy reserve and is stored in the liver and muscles. The other options (a) Lactose, (b) Cellulose, and (c) Glucose are not stored as polysaccharides in animals.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
