Questions: Multiple Choice Question Zinc is necessary for which of the following? Wound healing Vision Hair growth

The answer is the first one: wound healing.

Explanation for each option:

1. Wound healing: Zinc plays a crucial role in wound healing. It is involved in various aspects of cellular metabolism and is necessary for the function of over 300 enzymes. Zinc is essential for protein synthesis, cell division, and immune function, all of which are critical processes in wound healing.

2. Vision: While zinc is important for vision, particularly in maintaining the health of the retina and possibly slowing the progression of age-related macular degeneration, it is not as directly associated with vision as it is with wound healing.

3. Hair growth: Zinc does play a role in hair growth and repair, as it is involved in the production of DNA and RNA, which are necessary for the division and function of hair follicle cells. However, its role in wound healing is more critical and well-documented.

Summary: Zinc is necessary for wound healing, as it is involved in protein synthesis, cell division, and immune function, all of which are essential for the healing process.
