Animal starch is called:
Correct answer: C. Glycogen
- A. Cellulose
- B. Agar
- C. Glycogen
- D. Chitin
Explanation
Glycogen is the correct answer as it is the form of energy storage polysaccharide in animals, similar to starch in plants. It is a highly branched polymer of glucose. Cellulose, agar, and chitin serve different roles: cellulose provides structural support in plants, agar is used for its gelatinous properties, and chitin forms structural components in arthropods and fungi. None of these are used for energy storage 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.
