Question

Antibody production is an indispensible part of our immune response, but it is not the only defense our bodies have. Which of the following is observed during an infection that is not a result of antibody-antigen interactions?

(a) B cell proliferation
(b) aggregation of viral particles
(c) systemic temperature increase
(d) antibody secretion

Answer 1

During an infection, a systemic temperature increase (c) is an immune response that does not result from antibody-antigen interactions, whereas other options like B cell proliferation and antibody secretion are specifically tied to antibody production.

Step-by-step explanation:

The immune response includes both specific mechanisms, such as the production of antibodies by B cells, and non-specific mechanisms, such as fever. During an infection, one of the non-antibody related defenses that the body utilizes is a systemic temperature increase (c). This is part of the innate immune response and can hinder the replication of pathogens or activate other immune functions. Unlike B cell proliferation (a), aggregation of viral particles (b), and antibody secretion (d), the increase in body temperature is a non-specific defense that does not directly involve the activity of antibodies but rather is a systemic reaction to infection.
