Pre/Post Test – ELISA 1. Disease-causing agents such as viruses, bacteria, protozoa, molds and other microorganisms are called: a. antibodies; b. antigens; c. pathogens; d. microgens. 2. Your skin, respiratory system, digestive system, and circulatory system represent: a. first line defenses; b. nonspecific immunities; c. specific immunities; d. both a and b. 3. An antigen is: a. a protein or other molecule that can be separate or found on a pathogen and is foreign to your body; b. a protein made in response to a specific pathogen used to limit pathogen’s growth; c. a complex molecule that consists of serum proteins called immunoglobulins; d. a disease-causing molecule that produces immunity. 4. Which lymphocytes form antibodies? a. killer T cells; b. helper T cells; c. B cells; d. memory B cells. 5. All antibodies have the same basic _________________________ structure. a. H; b. Z; c. E; d. Y 6. An antibody is produced in response to a _____________________ antigen. a. reactive; b; specific; d. non-reactive; non-specific. 7. If a person has memory B cells against a certain pathogen, the person is: a. likely to develop that disease; b. much less likely to develop the disease a second time; c. able to spread the disease to others by physical contact; d. probably still sick with the disease. 8. What type of immunity is provided by a vaccine? a. inherited immunity; b. passive immunity; c. acquired immunity; d. none of the above. 9. Which of the following produce non-specific immune response to prevent infection? a. skin; b. saliva; c. tears; d. all of the above. 10. In the indirect ELISA test the enzyme-linked antibody will attach to: a. the patient antigen; b. the variable region of patient antibody; c. the constant region of the patient antibody; d. the wall of the microtiter well.
