The disaceharidase that produces same kind of monosaccharides upon hydrolysis

Options

A. maltase
B. sucrase
C. lactase
D. lipase

Answer

To solve the question regarding which disaccharidase produces the same kind of monosaccharides upon hydrolysis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a disaccharidase enzyme that, when it hydrolyzes its respective disaccharide, produces the same type of monosaccharides.

2. **Identify the Options**: The options given are:
- A. Maltase
- B. Sucrase
- C. Lactase
- D. Lipase

3. **Analyze Each Option**:
- **Maltase**: This enzyme acts on maltose, which is composed of two glucose molecules. When maltase hydrolyzes maltose, it produces two glucose monosaccharides. Thus, the result is two identical monosaccharides.
- **Sucrase**: This enzyme acts on sucrose, which is made up of glucose and fructose. Hydrolysis of sucrose by sucrase produces one molecule of glucose and one molecule of fructose, which are not the same.
- **Lactase**: This enzyme acts on lactose, which is composed of glucose and galactose. Hydrolysis of lactose by lactase yields one molecule of glucose and one molecule of galactose, which are also not the same.
- **Lipase**: This enzyme is involved in the hydrolysis of fats and does not act on carbohydrates, so it is not relevant to this question.

4. **Conclusion**: The only enzyme that produces the same kind of monosaccharides upon hydrolysis is **Maltase**, as it yields two molecules of glucose from maltose.

### Final Answer:
The disaccharidase that produces the same kind of monosaccharides upon hydrolysis is **A. Maltase**.
