What term refers to nutrients required in small amounts to maintain certain physiological functions?

The term that refers to nutrients required in small amounts to maintain certain physiological functions is micronutrients. Micronutrients include vitamins and minerals, which are essential for various bodily processes, including growth, development, and metabolism. They play critical roles in enzyme activity, immune function, and overall health.

Choosing micronutrients highlights that, despite being needed in smaller quantities compared to macronutrients (such as carbohydrates, proteins, and fats), these nutrients are vital for health and well-being. A deficiency in micronutrients can lead to significant health issues, emphasizing their importance even in small amounts.

While vitamins and minerals fall under the category of micronutrients, the broader term encompasses both, making it the most appropriate choice in this context. Macronutrients, on the other hand, refer to the energy-providing nutrients needed in larger amounts, which is a different classification entirely.
