Which of the following is a polysaccharide present in human muscle?
Correct answer: D. Glycogen
- A. Amylose
- B. Myoglobin
- C. Collagen
- D. Glycogen
Explanation
The correct answer is Glycogen. It is a polysaccharide stored in human muscles, playing a vital role in energy storage. Glycogen can be quickly converted to glucose, providing a readily available energy source during physical exertion.Amylose is incorrect because it is a plant-based polysaccharide found in starch, not in human muscles. Myoglobin and Collagen are not carbohydrates; Myoglobin is a protein involved in oxygen transport within muscles, and Collagen is a structural protein found in connective tissues.

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.
