What is zinc's role in immune function and wound healing?

• A. Zinc acts as a cofactor for many enzymes, supports immune function, and is important for wound healing and protein synthesis.
• B. Zinc provides the energy source for cells.
• C. Zinc stores vitamins within the liver.
• D. Zinc is a primary component of blood glucose.

Answer: (D)

Zinc serves as a crucial cofactor for many enzymes and is essential for immune function and wound healing. As a cofactor, zinc supports enzymes involved in DNA synthesis and protein production, which are needed for cell division, tissue repair, and the body’s immune responses. It also helps support the development and function of immune cells, such as T lymphocytes and phagocytes, and it aids in collagen formation and epithelialization during wound healing. It is not an energy source, does not store vitamins in the liver, and is not a primary component of blood glucose. So the best description of zinc’s role emphasizes its function as a cofactor for enzymes and its importance for immune defense, tissue repair, and protein synthesis.
