Final answer:
The main types of complex carbohydrates include starch, glycogen, and fiber, with glucose being a simple sugar and not a complex carbohydrate. The correct answer to the question is option 2) glucose.
Step-by-step explanation:
Complex carbohydrates, also known as polysaccharides, are large molecules composed of chains of monosaccharides. The main types of complex carbohydrates or polysaccharides include starch, glycogen, and fiber (cellulose). Starch, found in plants, serves as energy storage and can be found in foods like potatoes, bread, and pasta. Glycogen is similar to starch but is produced by animals and fungi for energy storage, playing a critical role in regulating blood glucose levels. Fiber, particularly cellulose, is a component in plant cell walls that aids in digestive health but does not provide energy. In contrast, glucose is a simple sugar and not a complex carbohydrate.
Therefore, the correct answer to the question is option 2) glucose, as it is a monosaccharide, not a complex carbohydrate.
