antigen-antibody reactions

Question 1

the presence of foreign agent or antigen stimulates the __ to produce antibdoy molecules, which directly bind with specific conformational areas on the antigen

Answer 1

b-lymphocytes

Question 2

the interaction of an immunoglobulin or antibody’s fab with the epitope of an antigen triggers a variety of immunological and chemical reactions are classified into: (3)

Answer 2

primary, secondary, and tertiary reaction

Question 3

reaction which refers to the actual binding that occurs between the individual antigenic determinants of antigens and the appropriate combining sites in the antibody molecules

Answer 3

primary reaction

Question 4
