Vitamins are necessary to ___________ energy from carbohydrates, fats, and proteins.

Vitamins play a crucial role in converting carbohydrates, fats, and proteins into energy. This process involves various biochemical reactions in the body where vitamins act as coenzymes or cofactors. For instance, B vitamins are integral in the metabolic pathways that extract energy from these macronutrients.

When you consume food, the body must transform it into usable energy; this transformation requires the presence of certain vitamins that assist in the enzymatic reactions necessary for energy release. Therefore, the action of vitamins in this context is to facilitate the release of energy from food sources, highlighting their essential role in metabolism. This is also why a well-balanced diet rich in vitamins is important for maintaining optimal energy levels and overall health.
