NEET BIOLOGY

Detailed explanation-1: -Animals store excess sugar in the form of glycogen. Plants store excess sugar in the form of starch. Both glycogen and starch are polysaccharides.

Detailed explanation-2: -After a meal, glucose enters the liver and levels of blood glucose rise. This excess glucose is dealt with by glycogenesis in which the liver converts glucose into glycogen for storage. The glucose that is not stored is used to produce energy by a process called glycolysis.

Detailed explanation-3: -Plants cannot store glucose as it is, but store in the form of starch because glucose is insoluble in water.

Detailed explanation-4: -Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants. It has a structure similar to amylopectin (a component of starch), but is more extensively branched and compact than starch.
