Which of the following best describes the structure of a carbohydrate molecule?

A chain of amino acids linked by peptide bonds

A chain of nucleotides linked by phosphodiester bonds

A chain of monosaccharides linked by glycosidic bonds

A chain of fatty acids linked by ester bonds

Answer explanation

Carbohydrates are composed of monosaccharides, which are simple sugars. These monosaccharides are linked together by glycosidic bonds to form larger carbohydrate molecules, making this the correct description.

Which functional group is commonly found in carbohydrates and is responsible for their solubility in water?

Carboxyl group

Hydroxyl group

Amino group

Phosphate group

Answer explanation

The hydroxyl group (-OH) is a functional group commonly found in carbohydrates. Its presence increases the solubility of carbohydrates in water due to hydrogen bonding, making it essential for their biological functions.

Explain how the structure of cellulose contributes to its function in plant cell walls.

The branched structure allows for easy storage and quick energy release.

The linear, unbranched structure forms strong fibers that provide rigidity.

The helical structure allows for compact storage in plant cells.

The globular structure makes it soluble in water for easy transport.

Answer explanation

The linear, unbranched structure of cellulose allows it to form strong fibers through hydrogen bonding, providing rigidity and structural support to plant cell walls, which is essential for maintaining plant shape and resisting external pressures.

Which of the following polysaccharides is primarily used for energy storage in animals?

Cellulose

Glycogen

Starch

Chitin

Answer explanation

Glycogen is the primary polysaccharide used for energy storage in animals, stored mainly in the liver and muscles. In contrast, cellulose is a structural component in plants, starch is used for energy storage in plants, and chitin is found in exoskeletons.

Which of the following is a disaccharide formed from two glucose molecules?

Lactose

Sucrose

Maltose

Fructose

Answer explanation

Maltose is a disaccharide formed from two glucose molecules. In contrast, lactose is made from glucose and galactose, sucrose from glucose and fructose, and fructose is a monosaccharide.

Describe the role of chitin in the biological systems where it is found.

It serves as an energy storage molecule in plants.

It provides structural support in the exoskeletons of arthropods.

It acts as a transport molecule in the bloodstream.

It functions as a signaling molecule in cellular communication.

Answer explanation

Chitin is a key structural component in the exoskeletons of arthropods, providing rigidity and protection. It is not involved in energy storage, transport, or signaling, making the second choice the correct answer.
