Zinc is an essential trace mineral necessary for which functions?

• A. Synthesis of granulation tissue and re-epithelialization, with anti-inflammatory and antimicrobial effects
• B. Role in vitamin A metabolism only
• C. Primary energy production
• D. Bone mineralization only

Answer: (A)

Zinc is essential for wound healing and immune defense. It acts as a critical cofactor for enzymes involved in DNA synthesis, cell proliferation, and protein synthesis, which are all necessary for making granulation tissue and for re-epithelialization of a wound. Zinc also helps modulate the inflammatory response and supports the integrity of the skin barrier, contributing to anti-inflammatory effects and a stronger antimicrobial defense within the healing tissue. The statement describing synthesis of granulation tissue and re-epithelialization, with anti-inflammatory and antimicrobial effects, captures these primary roles of zinc in tissue repair and host defense, making it the best fit. Other options don’t fit as well because zinc’s primary, well-established functions extend beyond vitamin A metabolism alone, are not centered on energy production, and are not limited to bone mineralization. Zinc contributes to many aspects of healing and immune function, not just one isolated task.
