Riboflavin is essential for which of the following bodily functions?

Riboflavin, also known as vitamin B2, plays a critical 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 essential for various biochemical reactions, particularly in the electron transport chain, which is a crucial process in cellular respiration. Through these reactions, riboflavin aids in the conversion of carbohydrates, fats, and proteins into energy, particularly ATP (adenosine triphosphate), which is the primary energy currency of the cell.

Energy production is vital for the proper functioning of all cells, and without adequate riboflavin, these processes can be hindered, leading to decreased energy levels and potential metabolic issues. Therefore, riboflavin’s role in facilitating energy production underscores its essentiality in maintaining overall health and metabolic functions.

While riboflavin does have indirect roles in carbohydrate metabolism and may assist in the metabolism of fats and proteins, its primary and most significant function is in energy production, making that the correct answer.
