Form of polysaccharides stored in bacteria and animals:
Correct answer: C. Glycogen
- A. Starch
- B. Cellulose
- C. Glycogen
- D. Chitin
Explanation
Glycogen is stored in both bacteria and animals. It serves as a primary energy storage molecule, a glucose polymer, in both organisms, with animals storing it mainly in the liver and muscles. In animals Location: Glycogen is primarily stored in the liver and muscle tissue.Function: It serves as a short-term energy reserve.Liver: Provides glucose to the bloodstream to maintain blood sugar levels between meals.Muscles: Provides glucose for the muscle cells' own energy needs during physical activity. In bacteria Location: Bacteria store glycogen within their cells.Function: It serves as a readily available source of carbon and energy that can be used when nutrients are scarce.

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.
