Question

Quizplus · Accepted Answer

Zinc is an essential nutrient that is important for many physiological processes such as wound healing, immune function, and DNA synthesis. However, excessive intake of zinc can lead to toxicity. Options A, B, and D are all true and established effects of zinc toxicity, but option C is false. Zinc competes with copper, not iron, for binding sites on superoxide dismutase, an antioxidant enzyme. This interference can cause copper deficiency, leading to neurological symptoms.
