Enzyme which has the fibrinolytic effect is

Options

A. protease
B. amylase
C. lipase
D. streptokinase

Answer

To solve the question regarding which enzyme has a fibrinolytic effect, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Fibrinolytic Effect":**
- Fibrinolytic refers to the process of breaking down fibrin, a protein involved in blood clotting. This process is crucial for preventing and dissolving blood clots in the vascular system.

2. **Identify the Enzymes Listed in the Question:**
- The options provided are:
- A) Protease
- B) Amylase
- C) Lipase
- D) Streptokinase

3. **Analyze Each Enzyme:**
- **Protease:** This enzyme breaks down proteins into smaller peptides or amino acids. It does not have a fibrinolytic effect.
- **Amylase:** This enzyme catalyzes the hydrolysis of starch into sugars. It does not have a fibrinolytic effect.
- **Lipase:** This enzyme is responsible for the hydrolysis of fats into fatty acids and glycerol. It does not have a fibrinolytic effect.
- **Streptokinase:** This enzyme is known for its ability to activate plasminogen, which leads to the breakdown of fibrin and thus has a fibrinolytic effect.

4. **Conclusion:**
- Based on the analysis, the enzyme that has the fibrinolytic effect is **Streptokinase**.

### Final Answer:
The enzyme which has the fibrinolytic effect is **Streptokinase** (Option D).
