The polysaccharides made up of glucose monomers are

Options

A. sucrose, lactose, maltose
B. chitin, glycogen, starch
C. starch, glycogen, cellulose
D. starch, inulin, peptidoglycan.

Answer

To answer the question about which polysaccharides are made up of glucose monomers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Polysaccharides**:
- Polysaccharides are large molecules formed by the polymerization of monosaccharides. They consist of many monosaccharide units linked together by glycosidic bonds.

2. **Analyzing the Options**:
- **Option A**: Sucrose, lactose, and maltose.
- These are disaccharides, not polysaccharides. Sucrose is made of glucose and fructose, lactose is made of glucose and galactose, and maltose is made of two glucose units. Thus, this option does not qualify.

- **Option B**: Chitin, glycogen, and starch.
- Chitin is made of N-acetylglucosamine, not glucose. Glycogen and starch are both polysaccharides made of glucose. Therefore, this option is partially correct but not entirely made up of glucose.

- **Option C**: Starch, glycogen, and cellulose.
- All three of these are polysaccharides made entirely of glucose monomers. Starch is a storage form of glucose in plants, glycogen is the storage form in animals, and cellulose is a structural component in plant cell walls made of glucose.

- **Option D**: Starch, inulin, and peptidoglycan.
- Starch is made of glucose, but inulin is a polymer of fructose, and peptidoglycan contains N-acetylglucosamine and N-acetylmuramic acid. Thus, this option does not qualify.

3. **Conclusion**:
- The correct answer is **Option C: Starch, glycogen, and cellulose**, as all of these polysaccharides are composed of glucose monomers.

### Final Answer:
The polysaccharides made up of glucose monomers are **starch, glycogen, and cellulose**.
