Cellulose is polymer of

Options

A. glucose
B. fructose
C. ribose
D. sucrose

Explanation

To solve the question "Cellulose is a polymer of," we will follow these steps:

### Step 1: Understand what a polymer is
A polymer is a large molecule composed of many repeated subunits, known as monomers. In the case of cellulose, we need to identify the specific monomer that makes up this polymer.

**Hint:** Recall that polymers are formed from repeating units of smaller molecules.

### Step 2: Identify the options given
The options provided are:
- Glucose
- Fructose
- Ribose
- Sucrose

**Hint:** Look for the common characteristics of these sugars and their structures.

### Step 3: Know the structure of cellulose
Cellulose is a polysaccharide that consists of long chains of beta-D-glucose units. These glucose units are linked together by glycosidic bonds, specifically between the C1 and C4 carbon atoms of adjacent glucose molecules.

**Hint:** Remember that cellulose is a structural component in plant cell walls and is made up of a specific type of glucose.

### Step 4: Analyze the options
- **Glucose:** This is a monosaccharide that can polymerize to form cellulose.
- **Fructose:** This is a different monosaccharide and does not form cellulose.
- **Ribose:** This is a pentose sugar, not related to cellulose.
- **Sucrose:** This is a disaccharide made of glucose and fructose, but not a polymer itself.

**Hint:** Think about which of these sugars can link together to form long chains.

### Step 5: Conclusion
Based on the analysis, the correct answer is that cellulose is a polymer of **glucose**.

**Final Answer:** Cellulose is a polymer of glucose.
