Self Quiz for The Adaptive Immune System: WaysThat Antibodies Defend the Body - Neutralization of Exotoxins

Study the material in this section and then write out the answers to these questions.
Do not just click on the answers and write them out. This will not test your understanding of this tutorial.

1. Discuss how antibodies defend the body by way of neutralizing exotoxins. (Include what classes or isotypes of immunoglobulins are involved, the role of the Fab portion of the antibody, the role, if any, of the Fc portion of the antibody, and the role of any complement proteins, if any, involved.) (ans)

2. Describe how the ability of Pseudomonas aeruginosa to sense its own population density, communicate with other Pseudomonas by way of secreted factors (cell-to-cell signaling), and behave as a population rather than as individual bacteria most likely plays an important role in pathogenicity of this organism. (ans)

3. Multiple Choice (ans)
