Which of the following does not contain amino acids?
Correct answer: B. Glycogen
- A. Carbonic anhydrase
- B. Glycogen
- C. Haemoglobin
- D. Insulin
Explanation
Glycogen is a complex carbohydrate and a form of energy storage in animals, including humans. It is often referred to as animal starch because of its similarity to starch, which is the storage form of carbohydrates in plants. Glycogen is primarily stored in the liver and muscles, and it serves as a readily available source of glucose for the body's energy needs. Glycogen is a polysaccharide composed of many glucose molecules linked together in a branched structure. It is a highly branched molecule, which allows for quick and efficient breakdown when the body requires glucose.

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.
