Question

Identify the polysaccharide among the following:

• A. Fructose
• B. Maltose
• C. Glucose
• D. Cellulose

Hint:

Examples of polysaccharides: Starch, Glycogen, Cellulose. All are polymers of glucose.

Answer 1

The Correct Option is D

To identify the polysaccharide among the given options, let's first understand what a polysaccharide is.

Concept Explanation:

Polysaccharides are large molecules composed of many monosaccharide units joined together by glycosidic bonds. They are also known as complex carbohydrates. Common examples include starch, glycogen, and cellulose.

Let's analyze each option:

1. Fructose: Fructose is a monosaccharide, which means it is a simple sugar consisting of a single sugar unit. Therefore, it is not a polysaccharide.
2. Maltose: Maltose is a disaccharide, composed of two glucose molecules. Since it only contains two sugar units, it is not considered a polysaccharide.
3. Glucose: Glucose is also a monosaccharide. Like fructose, it consists of a single sugar unit and is not a polysaccharide.
4. Cellulose: Cellulose is a polysaccharide composed of long chains of glucose units. It is a structural component of the cell walls in plants and is indeed a complex carbohydrate.

Conclusion:

Among the given options, cellulose is the only polysaccharide.

Correct Answer: Cellulose
