Which term describes a group of proteins that combine with antibodies to dissolve pathogens?

The term that describes a group of proteins that combine with antibodies to dissolve pathogens is "complement." The complement system is part of the immune response and consists of a series of proteins that enhance the ability of antibodies and phagocytic cells to clear pathogens from an organism. By binding to antibodies, complement proteins can trigger a cascade of reactions that lead to the destruction of pathogens.
