Question

The secondary response in antibody-mediated immunity

• A. Is characterized by a slow rise in antibody levels and then a gradual decline
• B. Is an intense response by memory cells to produce antibodies when an antigen is contacted again
• C. Occurs when you first receive a vaccination against some disease
• D. Produces fewer but more responsive antibodies that occur during the primary response

Answer 1

Answer: (B)

Is an intense response by memory cells to produce antibodies when an antigen is contacted again

Secondary response occurs when the body is second time exposed to the already infected antigen. At this time the memory cells recognize the antigen and immediately start secreting the antibodies for the antigen.

So, the correct option is 'Is an intense response by memory cells to produce antibodies when an antigen is contacted again'.
