Which of the followidg enzymes produce fructose upon hydrolysis?

Options

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

Answer

To determine which enzyme produces fructose upon hydrolysis, we can analyze the function of each enzyme mentioned in the question. Here’s a step-by-step breakdown:

### Step 1: Identify the enzymes and their substrates
- **Maltase**: This enzyme breaks down maltose, which is a disaccharide composed of two glucose molecules.
- **Lipase**: This enzyme hydrolyzes fats (lipids) into free fatty acids and glycerol, not carbohydrates.
- **Lactase**: This enzyme breaks down lactose, which is a disaccharide made of glucose and galactose.
- **Invertase**: This enzyme hydrolyzes sucrose, which is a disaccharide composed of glucose and fructose.

### Step 2: Analyze the products of each enzyme
- **Maltase** produces two molecules of glucose upon hydrolysis of maltose.
- **Lipase** does not produce any sugars; it produces fatty acids and glycerol.
- **Lactase** produces glucose and galactose upon hydrolysis of lactose.
- **Invertase** produces glucose and fructose upon hydrolysis of sucrose.

### Step 3: Determine which enzyme produces fructose
From the analysis, we see that:
- Only **Invertase** produces fructose as one of its products when it hydrolyzes sucrose.

### Conclusion
The enzyme that produces fructose upon hydrolysis is **Invertase**.

### Final Answer
**Invertase** is the enzyme that produces fructose upon hydrolysis.
