What is the main role of an antibody?

Causes bacterial growth
Serves as a remedy for poison
Counteract the effects of disease-producing bacteria or viruses
Induces allergic reactions

The correct answer is: Counteract the effects of disease-producing bacteria or viruses

Antibodies play a crucial role in the immune system by identifying and neutralizing pathogens such as bacteria and viruses. They are specialized proteins produced by B cells in response to antigens, which are foreign substances that provoke an immune response. By binding to these pathogens, antibodies can block their ability to infect cells, mark them for destruction by other immune cells, or neutralize their harmful effects. This function of counteracting the effects of disease-producing bacteria or viruses is essential for defending the body against infections and maintaining overall health. Antibodies are also involved in other aspects of the immune response, including the activation of complement proteins that enhance their ability to fight infections. While antibodies can have various interactions and effects within the immune system, their primary role remains in the protection against pathogens, making the statement about their function to counteract disease-producing agents accurate and significant.
