Cellulose, starch and glycogen are all the polysaccharides which contain:

Options

A. amylopectin and glycogen
B. amylose and glycogen
C. amylose and amylopectin
D. cellulose and glycogen

Explanation

To solve the question regarding the polysaccharides cellulose, starch, and glycogen, we will analyze each of these compounds step by step.

### Step-by-Step Solution:

1. **Identify the Polysaccharides**:
- The three polysaccharides in question are cellulose, starch, and glycogen.

2. **Source of Polysaccharides**:
- **Cellulose**: Found in the cell walls of plants.
- **Starch**: A storage form of glucose in plants, composed of two components: amylose and amylopectin.
- **Glycogen**: A storage form of glucose in animals.

3. **Subunits of Polysaccharides**:
- **Cellulose**: Composed of beta-glucose units.
- **Starch**: Composed of alpha-glucose units (both amylose and amylopectin are made of alpha-glucose).
- **Glycogen**: Also composed of alpha-glucose units.

4. **Structure of Starch**:
- **Amylose**: A linear polymer of alpha-glucose linked by 1,4-glycosidic bonds.
- **Amylopectin**: A branched polymer of alpha-glucose with both 1,4 and 1,6-glycosidic bonds.

5. **Comparison of Bonding**:
- **Cellulose**: Contains 1,4-glycosidic bonds between beta-glucose units.
- **Starch**: Contains 1,4-glycosidic bonds in amylose and both 1,4 and 1,6-glycosidic bonds in amylopectin.
- **Glycogen**: Contains 1,4 and 1,6-glycosidic bonds, similar to amylopectin but with more branching.

6. **Branching**:
- **Cellulose**: No branching.
- **Starch**: Amylose is unbranched, while amylopectin is branched.
- **Glycogen**: Highly branched structure.

7. **Conclusion**:
- The correct answer to the question is that cellulose, starch, and glycogen all contain **alpha-glucose** (in the case of starch and glycogen) and **beta-glucose** (in the case of cellulose). However, the question specifically asks for the components of starch, which are amylose and amylopectin.

### Final Answer:
The correct option is **C: Amylose and Amylopectin**.
