AMT MLS Domain 5: Immunology and Serology Welcome to your AMT MLS Domain 5: Immunology and Serology 1. AMT MLS: Immunology and Serology Which of the following best describes the primary role of the complement system in the immune response? Direct neutralization of viruses Phagocytosis of bacteria Lysis of foreign cells Presentation of antigens to T cells None 2. AMT MLS: Immunology and Serology In immunoelectrophoresis, what is the significance of the rocket pattern formed by the antigen-antibody precipitation? It indicates the purity of the antigen. It quantifies the amount of antigen. It determines the isoelectric point of the antigen. It identifies the specific class of the antibody. None 3. AMT MLS: Immunology and Serology Which molecule is essential for the activation of the classical pathway of the complement system? C3b C1q Factor B Properdin None 4. AMT MLS: Immunology and Serology What is the primary function of the Fc region of an antibody? Binding to antigens Mediating complement activation Facilitating membrane transport Assisting in antibody diversification None 5. AMT MLS: Immunology and Serology In the context of serological testing, what does the term "avidity" refer to? The speed of antigen-antibody binding The strength of the collective binding of a multivalent antibody to a multivalent antigen The specificity of an antibody to a particular antigen The ability of an antigen to elicit an immune response None 6. AMT MLS: Immunology and Serology Which of the following best defines a polyclonal antibody response? Antibodies produced by a single clone of B cells Antibodies that target a single epitope Antibodies produced by multiple B cell clones in response to a single antigen A response that generates antibodies against multiple antigens None 7. AMT MLS: Immunology and Serology What role does the J chain play in immunoglobulin structure? It facilitates the transport of IgA across epithelial cells. It is involved in the class switching of antibodies. It stabilizes the structure of the antibody's variable region. It enhances the antigen-binding affinity of the antibody. None 8. AMT MLS: Immunology and Serology In the ELISA technique, what is the purpose of adding a substrate after the enzyme-conjugated antibody? To visualize the antibody-antigen complexes To stabilize the antibody-antigen binding To neutralize unbound antibodies To detach the antibody from the plate None 9. AMT MLS: Immunology and Serology What is the significance of the Fc receptor on phagocytic cells? It recognizes and binds to the Fab region of antibodies. It mediates the uptake and destruction of pathogens. It is involved in the release of cytokines. It prevents the non-specific binding of antibodies. None 10. AMT MLS: Immunology and Serology In a Western blot test, what is the purpose of transferring proteins from a gel to a membrane? To separate proteins by size To enhance the sensitivity of antigen detection To facilitate the binding of antibodies to proteins To preserve the proteins for long-term storage None 1 out of 10 Time is Up!
