A patient has developed a clot in his heart. Which of these enzymes can be used to bust this clot ?

Options

A. Amylase
B. Streptokinase
C. Pectinase
D. Protease

Answer

To solve the question regarding which enzyme can be used to bust a clot in the heart, we can follow these steps:

### Step 1: Understand the Problem
The question states that a patient has developed a clot in the heart. We need to identify which enzyme from the given options can effectively dissolve or bust this clot.

### Step 2: Analyze the Options
The options provided are:
1. Amylase
2. Streptokinase
3. Pectinase
4. Protease

### Step 3: Identify the Function of Each Enzyme
- **Amylase**: This enzyme is responsible for breaking down starches into sugars. It is not involved in clot dissolution.
- **Streptokinase**: This is a thrombolytic enzyme that helps dissolve blood clots. It is produced by the bacteria Streptococcus and is used in medical settings to treat conditions like myocardial infarction (heart attack) and pulmonary embolism.
- **Pectinase**: This enzyme breaks down pectin, a substance found in plant cell walls. It is not related to clot dissolution.
- **Protease**: While proteases break down proteins, they are not specifically used to dissolve blood clots.

### Step 4: Determine the Correct Answer
Among the options, **Streptokinase** is the only enzyme that is specifically used to bust clots in the heart. It is a thrombolytic agent that can effectively dissolve clots.

### Final Answer
The correct enzyme that can be used to bust the clot in the heart is **Streptokinase**.
