Which of the following is NOT a function of vitamins?

Vitamins are essential organic compounds that play a crucial role in various bodily functions. They serve as regulators of body processes, supporting everything from immune function to metabolism. The correct answer indicates that providing large amounts of energy is not a function of vitamins. While they are integral to energy metabolism, vitamins do not directly provide energy in the way macronutrients like carbohydrates, fats, and proteins do.

Vitamins are required in very small amounts, reflecting their role as micronutrients that facilitate biochemical reactions without being consumed in the process. Additionally, they support normal growth and development, which is vital for maintaining health throughout different life stages. Therefore, while vitamins contribute significantly to overall health, they do not function as direct energy sources, which makes the identification of providing large amounts of energy as outside their function accurate.
