What is another term for gamma globulins?

• A. Cytokines
• B. Immunoglobulins
• C. Proteins
• D. Enzymes

Answer: (B)

Gamma globulins are primarily known as immunoglobulins, which are antibodies produced by plasma cells in the immune system. These specialized proteins play a critical role in identifying and neutralizing foreign objects like bacteria and viruses. The term "immunoglobulins" specifically refers to the functional aspect of these proteins, highlighting their role in immune defense. There are several classes of immunoglobulins (IgA, IgD, IgE, IgG, and IgM), each serving distinct functions in the immune response.

In contrast, cytokines refer to signaling proteins that are involved in cell communication during immune responses, proteins encompass a broader category of macromolecules that include enzymes and structural proteins, and enzymes are proteins that catalyze biochemical reactions. While gamma globulins are indeed proteins, the answer focuses specifically on their role as antibodies, making "immunoglobulins" the more precise term in this context.
