How do activated B cells help defend against pathogens?

Activated B cells play a crucial role in defending against pathogens by producing antibodies, which are proteins that specifically recognize and bind to foreign antigens, such as those found on the surface of bacteria, viruses, or other pathogens. The process begins when B cells encounter a pathogen or pathogen-derived molecule. These B cells possess membrane-bound immunoglobulins (Ig) that act as receptors for antigens. ______ ______ ___ ____ __________ ____ ________ __________ _______ _______ ________ _________.
