What is the primary function of carbohydrates in the body?

• A. Provide energy
• B. Build muscle
• C. Regulate body temperature
• D. Enhance immune function

Answer: (A)

The primary function of carbohydrates in the body is to provide energy. Carbohydrates are one of the three macronutrients, along with proteins and fats. When consumed, carbohydrates are broken down into glucose, which is then utilized by the body’s cells as a key source of fuel. This process is especially important for high-energy-demanding organs such as the brain and muscles during physical activity. Although carbohydrates serve other roles, their main contribution to nutrition is energy production. The body can store excess carbohydrates in the form of glycogen in the liver and muscles, which can be rapidly mobilized when energy is needed. This quick conversion to energy supports both day-to-day activities and exercise. In contrast, the other functions listed, such as building muscle, regulating body temperature, and enhancing immune function, are primarily associated with proteins and fats or are part of broader bodily processes rather than the specific role of carbohydrates. Therefore, understanding the fundamental role of carbohydrates in energy provision is essential in the study of nutrition and its impact on overall health.
