What product of immune system attaches to bacteria making them prone to be eliminated by white blood cells

Options

A. Antigen
B. Haemoglobin
C. Antibody
D. MHC I moleucle

Answer

**Step-by-Step Solution:**

1. **Understanding the Immune System**: The immune system is responsible for protecting the body against foreign invaders, such as bacteria and viruses. It consists of various cells and proteins that work together to identify and eliminate these pathogens.

2. **Role of White Blood Cells**: White blood cells (WBCs) are crucial components of the immune system. They identify and attack foreign substances in the body, including bacteria.

3. **Introduction of Antibodies**: When bacteria enter the body, the immune system responds by producing specific proteins known as antibodies. These antibodies are Y-shaped molecules that play a vital role in the immune response.

4. **Binding Mechanism**: The antibodies have specific sites that can bind to antigens, which are molecules found on the surface of bacteria (and other pathogens). This binding occurs at the tips of the Y-shaped antibody.

5. **Facilitating Elimination**: Once the antibodies bind to the bacteria, they mark these pathogens for destruction. This process makes the bacteria more recognizable to white blood cells, which can then eliminate them more effectively.

6. **Conclusion**: Therefore, the product of the immune system that attaches to bacteria and makes them prone to elimination by white blood cells is called an **antibody**.

**Final Answer**: Antibody
