Verified step by step guidance

Understand the classification of carbohydrates: Carbohydrates are divided into simple and complex types. Simple carbohydrates include monosaccharides (single sugar molecules) and disaccharides (two sugar molecules linked together). Complex carbohydrates consist of polysaccharides, which are long chains of sugar molecules.

Identify the examples of simple carbohydrates: Simple carbohydrates include glucose, fructose, sucrose, and lactose. These are typically small molecules that are easily digestible and provide quick energy.

Analyze the options provided: Glycogen and amylopectin are polysaccharides, making them complex carbohydrates. Cellulose and starch are also polysaccharides, and chitin and dextran are structural or storage polysaccharides, so none of these are simple carbohydrates.

Focus on glucose and fructose: Glucose and fructose are monosaccharides, which are classified as simple carbohydrates. They are small, single sugar molecules that serve as primary energy sources in biological systems.

Conclude that glucose and fructose are the correct answer: Based on the classification of carbohydrates, glucose and fructose fit the definition of simple carbohydrates, while the other options are examples of complex carbohydrates.
