Correct Response: C. Carbohydrates are the primary source of energy for most body functions. Glucose, formed as the body breaks down carbohydrates, is used by almost all body cells for energy, and excess is stored by the body in fat cells to provide energy as needed. Water levels are maintained in the body (A) by the actions of mineral salts or electrolytes, such as sodium and potassium. Protein is important for new cell growth and repair of damaged cells (B). Water and sodium are important for cooling the body temperature, and the sugars in excess carbohydrates can raise blood sugar levels (D).
