What is the primary function of carbohydrates in the body?

• A. To serve as the body’s main source of energy
• B. To repair tissues
• C. To increase muscle mass
• D. To enhance flexibility

Answer: (A)

The primary function of carbohydrates in the body is to serve as the main source of energy. When carbohydrates are consumed, they are broken down into glucose, which is a simple sugar. This glucose is then used by the body’s cells for immediate energy or stored in the liver and muscles as glycogen for later use. Adequate carbohydrate intake is essential for maintaining energy levels, especially during physical activity and exercise, as they provide a readily available fuel source. Carbohydrates play a critical role in the body’s metabolism and are particularly important for brain function since the brain primarily relies on glucose for energy. This makes them a crucial macronutrient in a balanced diet, supporting not just sustained physical activity but also cognitive processes. In contrast, options like repairing tissues, increasing muscle mass, and enhancing flexibility are functions primarily associated with proteins and other nutrients rather than carbohydrates.
