Which of the following nutrients is primarily responsible for providing energy?

Carbohydrates are the primary source of energy for the body. They are broken down into glucose, which is readily used by the body's cells to fuel various functions and activities. When consumed, carbohydrates are converted into energy, making them essential for physical activity and the body's overall metabolic processes.

Water, while crucial for maintaining hydration and supporting numerous bodily functions, does not provide calories and therefore is not a direct source of energy. Vitamins are organic compounds that support metabolic processes and help in energy production, but they themselves do not provide energy. Minerals, similar to vitamins, play vital roles in various biochemical reactions in the body, but they also do not provide direct energy. Thus, carbohydrates stand out as the vital macronutrient specifically responsible for delivering energy to the body.
