What is one of the primary roles of riboflavin in the body?

Riboflavin, also known as vitamin B2, plays a crucial role in energy production within the body. It is a key component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are vital in various metabolic processes, particularly in the oxidation-reduction reactions that occur during the breakdown of carbohydrates, fats, and proteins for energy. The presence of riboflavin is essential for the function of the electron transport chain, which is the primary pathway for aerobic energy production in cells.

The other roles mentioned, such as carbohydrate synthesis, cell membrane structure, and hormone regulation, do not directly relate to the primary functions of riboflavin. While a well-rounded diet with adequate riboflavin supports overall health, its critical function revolves around facilitating energy production through the aforementioned coenzymes.
