In an allergic reaction,allergens bind _____,which release allergy mediators.
A)IgE antibodies on mast cell surfaces
B)IgG antibodies on B cell surfaces
C)allergy genes on chromosome 5
D)histamines on mast cell surfaces

Question

Quizplus · Accepted Answer

Allergens bind to IgE antibodies on the surface of mast cells, which triggers the release of allergy mediators, such as histamines, leukotrienes, and cytokines. This leads to the symptoms of an allergic reaction. IgG antibodies are not involved in allergic reactions, and allergy genes on chromosome 5 may contribute to the development of allergies, but they are not directly involved in the binding of allergens to antibodies. Histamines are released by mast cells in response to allergen binding, but they are not the molecules that the allergens bind to.
