Abzymes are

Options

A. Abnormal enzymes
B. Enzymes acting on antibodies
C. Antibodies acting as enzymes
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Abzymes":**
- Abzymes are a type of molecule that combines the properties of antibodies and enzymes.

2. **Defining Enzymes:**
- Enzymes are biological catalysts that speed up biochemical reactions in living organisms.

3. **Defining Antibodies:**
- Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

4. **Identifying the Role of Abzymes:**
- Abzymes function as antibodies that can also catalyze biochemical reactions, similar to enzymes. This means they can help break down substances, such as viruses.

5. **Analyzing the Options:**
- Option 1: Abnormal Enzymes - This is incorrect as abzymes are not simply abnormal enzymes.
- Option 2: Enzymes acting on Antibodies - This is also incorrect since abzymes are not enzymes acting on antibodies.
- Option 3: Antibodies acting as Enzymes - This is correct as abzymes are indeed antibodies that have enzyme-like activity.
- Option 4: All of this - This is incorrect because not all the previous options are true.

6. **Conclusion:**
- The correct answer is that abzymes are "Antibodies acting as Enzymes."

**Final Answer:**
Abzymes are antibodies that act as enzymes.
