Final answer:
Among the options given, the types of polysaccharides are B. Fiber (cellulose), D. Starch, and E. Glycogen. Starch and glycogen are energy storage polysaccharides in plants and animals respectively, while fiber like cellulose is part of plant cell walls.
Step-by-step explanation:
Types of Polysaccharides
Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units linked together by glycosidic bonds. The most commonly known polysaccharides include starch, glycogen, and cellulose, which is often referred to as fiber. These polysaccharides are made up of glucose units, although they differ in structure: starch and glycogen are branched polymers, while cellulose is a linear chain. Specifically,
- Starch is a storage polysaccharide in plants, consisting of a mix of amylose and amylopectin.
- Glycogen, known as animal starch, is a storage polysaccharide in animals and bacteria, with a structure quite similar to amylopectin but more extensively branched.
- Fiber refers to a group of substances in plant foods that cannot be completely broken down by human digestive enzymes. One type of fiber is cellulose, a polysaccharide that is a major component of plant cell walls.
Therefore, among the options given, the types of polysaccharides are:
- B. Fiber (more specifically, cellulose)
- D. Starch
- E. Glycogen
