What is the key function of antibodies in the immune response?

• A. Increase Temperature
• B. Neutralize Toxins
• C. Produce Cytokines
• D. Promote Cell Division

Answer: (B)

The key function of antibodies in the immune response is to neutralize toxins. Antibodies are specialized proteins produced by B cells in response to antigens, such as pathogens or toxins. When antibodies bind to these antigens, they can neutralize the harmful effects of toxins directly, preventing them from interacting with host cells. This neutralization can block the ability of toxins to exert their harmful effects, thus offering protection to the body. Additionally, antibodies can enhance the immune response by marking pathogens for destruction by other immune cells through a process called opsonization, but their primary role when it comes to toxins is direct neutralization. This characteristic is critical in defending the body against various infectious agents and their byproducts, underscoring the important role antibodies play in the adaptive immune system.
