Starch is digested by

Options

A. Peptidase
B. Amylase
C. Lipase
D. Protiense

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which enzyme is responsible for the digestion of starch.

2. **Identifying the Options**: The options provided are:
- A) Peptidase
- B) Amylase
- C) Lipase
- D) Proteinase

3. **Analyzing Each Option**:
- **Peptidase**: This enzyme is involved in the digestion of proteins, not starch. Therefore, it is not the correct answer.
- **Amylase**: This enzyme is specifically responsible for the digestion of starch into simpler sugars like maltose. This is a strong candidate for the correct answer.
- **Lipase**: This enzyme is involved in the digestion of lipids (fats), so it is not relevant to starch digestion.
- **Proteinase**: Similar to peptidase, this enzyme also digests proteins and is not involved in starch digestion.

4. **Conclusion**: Since amylase is the enzyme that digests starch into maltose, the correct answer is **B) Amylase**.

5. **Additional Information**:
- Starch digestion begins in the mouth with salivary amylase and continues in the small intestine with pancreatic amylase.
- The end product of starch digestion is maltose, which can be further broken down into glucose.
