Which micronutrient is primarily responsible for many cell functions?

Vitamins are indeed the micronutrients that play a crucial role in numerous cellular functions. They serve as coenzymes or precursors for enzyme activation, which means they facilitate various biochemical reactions essential for maintaining cellular health. Each vitamin typically has a specific role; for example, B vitamins are vital in energy production, while vitamin C is significant for collagen synthesis and antioxidant functions.

Additionally, vitamins can affect processes such as immune response, growth and development, and metabolism. The diverse functions of different vitamins underscore their importance in supporting not just individual cell activity but overall bodily health. They are needed in small amounts, which is characteristic of micronutrients, contrasting them with macronutrients like carbohydrates and proteins that provide energy and serve as structural components in large quantities.
