a cellular immune response

Answer 107

a humoral immune response

Answer 108

an autoimmune response

Answer 109

the portion of an antibody which recognizes an antigen.

Answer 110

the protein of an antigen recognized by an antibody.

Answer 111

an internal signal in the B-lymphocytes initiating the production of antibodies.

Answer 112

The Fab fragment is capable of binding antigen but the Fc fragment is not.

Answer 113

The Fab fragment can bind antigen only in the presence of the Fc fragment.

Answer 114

The proteolytic action of papain abolishes the ability of the antibody fragments to bind antigen.

come from the H chain only.

Answer 120

come from both the H and L chains.

Answer 121
