Answer to Question 1

ANS: A, C, D, E
Immunoglobulin A (IgA) is found in high concentrations in secretions from mucous membranes. Immunoglobulin E (IgE) is associated with antibody-mediated hypersensitivity reactions. The majority of the circulating antibody population consists of immunoglobulin G (IgG). The first antibody formed by a newly sensitized B cell is immunoglobulin M (IgM). Immunoglobulin D (IgD) is typically present in low concentrations.

Answer to Question 2

ANS: A, B, D, E
The seven steps in the process of making antigen-specific antibodies are: exposure/invasion, antigen recognition, sensitization, antibody production and release, antigen-antibody binding, antibody binding actions, and sustained immunity. Opsonization is the adherence of an antibody to the antigen, marking it for destruction.
