Starch is present in tubers, fruits, and grains but absent in animal cells. Instead, animals have a substance stored in liver and muscles known as:
Correct answer: C. Glycogen
- A. Galactose
- B. Glucagon
- C. Glycogen
- D. Glucose
Explanation
Glycogen is the storage form of carbohydrate found in animals. Glycogen is the body's stored form of glucose, which is a type of sugar that serves as the main source of energy. It is a large, branched molecule made of many glucose units linked together, and it is stored primarily in the liver and muscles. When the body needs energy, glycogen is broken down to release glucose into the bloodstream for the cells to use.Galactose (A) is a monosaccharide, Glucagon (B) is a hormone, Glucose (D) is a monosaccharide and the monomer of glycogen and starch.

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.
