Starch is converted to maltose by

Options

A. Zymase
B. Maltase
C. Diastase
D. Invertase

Answer

To solve the question "Starch is converted to maltose by?", we need to identify the correct enzyme from the given options. Here’s a step-by-step solution:

### Step 1: Understand the Question
The question asks which enzyme is responsible for converting starch into maltose.

**Hint:** Focus on the specific conversion process mentioned in the question.

### Step 2: Analyze the Options
We have four enzymes to consider:
1. **Zymase**
2. **Maltase**
3. **Diastase**
4. **Invertase**

**Hint:** Look at the function of each enzyme to see which one matches the conversion of starch to maltose.

### Step 3: Evaluate Each Enzyme
- **Zymase:** This enzyme is involved in the fermentation process, converting glucose into alcohol. It does not convert starch to maltose.

**Hint:** Zymase is related to fermentation, not starch breakdown.

- **Maltase:** This enzyme converts maltose into glucose. It is not involved in the conversion of starch to maltose.

**Hint:** Maltase works on maltose, not starch.

- **Diastase:** This enzyme is known for its ability to hydrolyze starch into maltose. Therefore, it is the enzyme that converts starch into maltose.

**Hint:** Diastase is specifically related to starch breakdown.

- **Invertase:** This enzyme hydrolyzes sucrose into glucose and fructose, not starch into maltose.

**Hint:** Invertase deals with sucrose, not starch.

### Step 4: Conclusion
Based on the analysis, the correct enzyme that converts starch to maltose is **Diastase**.

**Final Answer:** Starch is converted to maltose by **Diastase**.
