Question

Antibody promotes the release of histamine, which triggers allergic reactions:

• A. IgA
• B. IgM
• C. IgE
• D. IgD

Answer 1

Answer:

C. IgE

When an allergen enters the body, it binds to IgE antibodies on the surface of mast cells and basophils. This sensitizes the cells to release histamine and other inflammatory mediators when they encounter the allergen again.
