Match the following antibody action with its correct description/function. Neutralization of microbial toxins Immobilization of bacteria Agglutination Complement activity Enhanced phagocytosis A. Antibodies and blood plasma proteins work together to "help" facilitate the immune response. B. Antibodies bind to multiple bacterial cells and make them clump. C. Antibodies bind to a toxic structure on the surface of a pathogen. D. Antibodies bind to flagella of motile bacteria. E. Antibodies bind to a microbe and facilitate its destruction by macrophages and other white blood cells.

Which of the following is NOT a way that antibodies work to remove pathogens? relocation (move antigens to the lymph system to be disposed of by other immune cells) inflammation (triggers histamine release) precipitation (makes soluble antigens insoluble) agglutination (clumps up antigens for easier disposal)

Match the Ig action with its definition. I will have to go in and manually score this one, so don't freak out if you get a zero initially.... I will check your answers and give you credit for the ones with the proper matches. An antibody with the ability to neutralize a specific substance produced by a plant or animal Antibodies bind with the pathogen and form antibody/pathogen complexes which incapacitate the pathogen by preventing it from communicating with other cells in the body The clumping of cells such as bacteria or red blood cells in the presence of an antibody or complement Antibodies bind to the pathogen and release a chemical to attract the phagocytic cells binding and marking intruders and by signaling this mechanism to begin with the end result of lysing the marked cell Neutralization Complement Activation Antitoxin Agglutination Opsonization
