The enzyme that converts starch into maltose is called

Options

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

Answer

To solve the question "The enzyme that converts starch into maltose is called," we can follow these steps:

### Step 1: Understand the Components
- **Starch** is a polysaccharide, which means it is made up of many sugar units.
- **Maltose** is a disaccharide, which consists of two sugar units.

### Step 2: Identify the Enzyme
- Enzymes that break down polysaccharides into simpler sugars typically have names that reflect the substrate they act upon.
- The enzyme that specifically breaks down starch is known as **amylase**.

### Step 3: Clarify the Function of Amylase
- Amylase catalyzes the hydrolysis of starch into maltose. This means it helps in breaking the bonds in starch to convert it into maltose.

### Step 4: Eliminate Other Options
- **Zymase** is involved in the fermentation process and does not convert starch to maltose.
- **Maltase** breaks down maltose into glucose, not starch into maltose.
- **Invertase** hydrolyzes sucrose into glucose and fructose, not starch.

### Conclusion
Thus, the enzyme that converts starch into maltose is called **amylase**.
