Which nutrient category includes starches and sugars that are converted to glucose for energy?

• A. Proteins
• B. Fats
• C. Carbohydrates
• D. Vitamins

Answer: (C)

Carbohydrates are the nutrient category that includes starches and sugars, and they’re converted to glucose to fuel the body’s energy needs. When you eat starches, your digestive system breaks them down into glucose molecules, and sugars go to glucose-ready forms. Glucose becomes ATP through cellular processes, making it the body’s main, readily available energy source, especially for the brain and muscles during activity. Excess glucose can be stored as glycogen in the liver and muscles or, if needed, can be turned into fat for longer-term storage. While proteins and fats can also provide energy in certain situations, they are not the primary source of quick energy in the form of glucose, which is why this category best fits the description.
