B1.1.5—Polysaccharides as energy storage Topic Practice
Practise how glucose polymers store energy, using structure, branching and glycosidic linkages to compare starch and glycogen.
How this is tested
- compare amylose and amylopectin using branching and glycosidic bonds
- explain why compact, insoluble polysaccharides work well as energy stores
- interpret diagrams to distinguish starch, glycogen and amylopectin structures
