Name a bacterium used as a clot buster. Also mention the enzyme.

Options

A. Ovulation
B. Development of secondary sexual characters
C. Spermatogenesis
D. Control of blood sugar

Answer

**Step-by-Step Solution:**

1. **Identify the Context**: The question asks for a bacterium that acts as a clot buster and the specific enzyme it produces. Clot busters are substances that help dissolve blood clots, which can lead to conditions like heart attacks or strokes.

2. **Name the Bacterium**: The bacterium used as a clot buster is **Streptococcus**. This bacterium is known for its role in producing substances that can help dissolve blood clots.

3. **Identify the Enzyme**: The specific enzyme produced by Streptococcus that acts as a clot buster is called **streptokinase**. This enzyme is crucial for its fibrinolytic action, meaning it helps to break down fibrin, a key component of blood clots.

4. **Explain the Mechanism**: Streptokinase works by activating the body's natural fibrinolytic system, which leads to the breakdown of clots in the blood vessels, thereby restoring normal blood flow.

5. **Summarize the Answer**: In summary, the bacterium used as a clot buster is **Streptococcus**, and the enzyme it produces is **streptokinase**.
