What is the function of globulin in blood?

• A. Involved in immunity, including alpha lipids and some metals, beta lipids and iron, and gamma antibodies.
• B. Primary component of the clotting cascade.
• C. Oxygen transport.
• D. Maintains osmotic pressure.

Answer: (A)

Globulins are a diverse group of plasma proteins. Among them, gamma globulins are the antibodies that defend the body by recognizing and neutralizing foreign invaders. The option describes immunity in connection with gamma antibodies, which captures the most fundamental role of globulins in the blood: providing immune defense through antibodies. Other major blood functions are carried out by different proteins: coagulation factors like fibrinogen drive the clotting cascade, not globulins; oxygen transport is the job of hemoglobin inside red blood cells; and osmotic pressure in plasma is largely determined by albumin rather than globulins.
