Which of the following is FALSE? O O O O Proteins with their ability to have a primary, secondary, tertiary or quaternary structure tend to be more antigenic than carbohydrates. Antibodies are substances that cause the body to produce specific sensitized T-cells. Hapten can combine with carrier molecules to illicit antibody production. Antigens are substances that illicit an antibody response. Stainless steel is an example of a material that is non-antigenic mainly due to its insolubility.
All of the following are true of the lymphatic system, EXCEPT: Lymphatic capillaries lie in close physical proximity to arterial and venous capillaries None of the other four answers (all are true of the lymphatic system) Lymph nodes are located at lymphatic vessel junctions It brings microbial antigens into contact with immunologically active cells (lymphocytes and macrophages) Its only important function is to carry interstitial fluid back to the circulatory system

Which of these does NOT describe complement? It is a type of antibody. It is an innate (non-specific) immune response. It can be activated by contact with the microbe’s cell surface. It destroys bacterial cells by lysis and by enhancing phagocytosis. It is a group of proteins found in the blood.
The figure below shows antibodies bound to repetitive epitopes on the surface of a bacterial pathogen. Even though all of these epitopes are identical, not all of them have antibodies bound to them. The most likely explanation for this failure of antibodies to bind to every possible epitope on the surface of the pathogen is: There is an insufficient amount of antibody to saturate all the epitopes. The pathogen has an immune evasion strategy to avoid antibody binding to all epitopes. Some of the epitopes cannot bind antibody due to steric hindrance. The antibodies are only able to bind when both antigen-binding sites are engaged on the pathogen surface. The epitopes on the pathogen are not all in the same conformation, so not all will bind the same antibody.
