Which substance is a simple carbohydrate?

• A. Starch
• B. Glycogen
• C. Fructose
• D. Fiber

Answer: (C)

Fructose is classified as a simple carbohydrate because it is a monosaccharide, meaning it consists of a single sugar unit. Simple carbohydrates are quickly absorbed by the body and provide immediate energy because they require little to no digestion before being utilized by our cells. Fructose is naturally found in fruits, honey, and root vegetables, contributing to their sweetness. As a simple sugar, it can readily enter the bloodstream, offering a rapid source of energy. In contrast, starch and glycogen are complex carbohydrates, as they are made up of multiple sugar units linked together. Starch serves as a storage form of energy in plants, while glycogen performs a similar function in animals. Fiber is also a complex carbohydrate but is not digested and absorbed in the same way, contributing primarily to digestive health rather than serving as a direct source of energy.
