Question

The chemical released by B cells after recognition of hapten - carrier complex is known as

• A. Antibodies
• B. Lymphokines
• C. Antigen
• D. All of the above

Answer 1

The correct option is A Antibodies

Haptens are low-molecular-weight compounds which may be bound by antibodies, but cannot elicit an immune response. Hence the haptens themselves are nonimmunogenic and cannot evoke an immune response until they bind to a larger carrier immunogenic molecule. The hapten-carrier complex act as an immunogen and induce an immune response. Hence the B cells produce antibodies specific to both the carrier and hapten. Thus the correct answer is option A.
