Starch is mixture of:

Options

A. amylon
B. amylopectin
C. maltase
D. lactose

Answer

To solve the question "Starch is a mixture of:", we need to identify the components that make up starch.

### Step-by-Step Solution:

1. **Understanding Starch**:
- Starch is a polysaccharide that serves as a storage form of energy in plants. It is analogous to glycogen in animals.

2. **Components of Starch**:
- Starch is primarily composed of two types of molecules: amylose and amylopectin.

3. **Amylose**:
- Amylose is a linear polymer made up of alpha-D-glucose units. It is known for being water-soluble.

4. **Amylopectin**:
- Amylopectin, on the other hand, is a highly branched polymer also made up of alpha-D-glucose units. Unlike amylose, amylopectin is water-insoluble.

5. **Conclusion**:
- Since starch consists of both amylose and amylopectin, the correct answer to the question is that starch is a mixture of amylose (Option A) and amylopectin (Option B).

### Final Answer:
Starch is a mixture of amylose and amylopectin.
