Which of the following set is a biopolymer of glucose ?

Options

A. Glycogen , sucrose , maltose
B. Glycogen , cellulose , starch
C. Sucrose, inulin , pectin
D. Glycogen, sucrose , lactose

Answer

To solve the question "Which of the following set is a biopolymer of glucose?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Biopolymers**:
- A biopolymer is a large molecule made up of repeating units (monomers). In this case, we are looking for polymers made specifically from glucose units.

2. **Analyzing the Options**:
- **Option 1: Glycogen, Sucrose, and Maltose**:
- Glycogen is a biopolymer of glucose, as it is a polysaccharide made up of glucose monomers.
- Sucrose is a disaccharide composed of glucose and fructose. It is not a biopolymer of glucose.
- Maltose is also a disaccharide made up of two glucose units. While it is made of glucose, it is not a biopolymer (which requires more than two monomers).
- **Conclusion**: This option is incorrect.

3. **Option 2: Glycogen, Cellulose, and Starch**:
- Glycogen is a biopolymer of glucose.
- Cellulose is a polysaccharide made of glucose monomers and is a major component of plant cell walls.
- Starch is another polysaccharide composed of glucose units and serves as a storage form of energy in plants.
- **Conclusion**: This option is correct as all three are biopolymers of glucose.

4. **Option 3: Sucrose, Inulin, and Pectin**:
- Sucrose, as mentioned, is not a biopolymer of glucose.
- Inulin is a polysaccharide made up of fructose units, not glucose.
- Pectin is a polysaccharide that primarily consists of galacturonic acid, not glucose.
- **Conclusion**: This option is incorrect.

5. **Option 4: Glycogen, Sucrose, and Lactose**:
- Glycogen is a biopolymer of glucose.
- Sucrose is not a biopolymer of glucose.
- Lactose is a disaccharide made of glucose and galactose.
- **Conclusion**: This option is incorrect.

### Final Answer:
The correct answer is **Option 2: Glycogen, Cellulose, and Starch**.
