A cellulose molecule is formed by the polymerization of glucose. The number of glucose molecules present in a cellulose is
(a) 600
(b) 6000
(c) 60000
(d) 60

Options

A. 600
B. 6000
C. 60000
D. 60

Answer

To solve the question regarding the number of glucose molecules present in a cellulose molecule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cellulose**:
- Cellulose is a type of carbohydrate known as a homopolysaccharide. It is primarily composed of glucose units.

2. **Structure of Cellulose**:
- Cellulose is characterized as a linear and unbranched polymer. This means that the glucose units are connected in a straight chain without any branching.

3. **Composition of Cellulose**:
- Each cellulose molecule is formed by the polymerization of many glucose molecules. Specifically, cellulose is made up of beta-glucose units.

4. **Number of Glucose Units**:
- It is known that a typical cellulose molecule consists of approximately 6,000 beta-glucose units linked together. These glucose units are connected by beta-1,4 glycosidic linkages.

5. **Choosing the Correct Option**:
- Given the options:
- (a) 600
- (b) 6000
- (c) 60000
- (d) 60
- Since cellulose is made up of about 6,000 glucose units, the correct answer is option (b) 6000.

### Final Answer:
The number of glucose molecules present in a cellulose molecule is **6000** (Option B).
