Zinc plays a critical role in nutrition, particularly in supporting immune function. This mineral is essential for the development and activation of T-cells, which are crucial to the adaptive immune response. Zinc also contributes to the production of various proteins, including those involved in the immune signaling pathways. Deficiencies in zinc can lead to impaired immune response, increased susceptibility to infections, and delayed wound healing, highlighting its importance in maintaining a healthy immune system.

The functions of zinc extend beyond immune support; however, its role in photosynthesis is not applicable, as this process primarily involves chlorophyll and plant structures. Additionally, zinc is not a primary energy source; energy comes mainly from macronutrients like carbohydrates, fats, and proteins. While zinc is vital for many physiological functions, claiming that it does not play a significant role overlooks its numerous contributions to health, especially its immunological implications.
