Verified step by step guidance

Understand the role of antibodies in the immune system. Antibodies are proteins produced by B cells that help to neutralize pathogens such as bacteria and viruses.

Identify the mechanisms of antibody action. Common mechanisms include neutralization, agglutination, and precipitation.

Neutralization involves antibodies binding to a pathogen to block its activity, preventing it from infecting cells.

Agglutination is the clumping of particles, which occurs when antibodies bind to antigens on the surface of pathogens, making them easier targets for phagocytes.

Precipitation involves antibodies binding to soluble antigens, causing them to form insoluble complexes that can be removed by phagocytes. B cell synthesis is not a mechanism of antibody action; it is the process by which B cells produce antibodies.
