Final answer:
Glycogen is the storage form of glucose in humans and other vertebrates, not in plants. Plants store glucose as starch. Glycogen in animals is broken down into glucose through glycogenolysis when needed.
Step-by-step explanation:
The statement that glycogen is the storage form of glucose in plants is false. In reality, glycogen is the main storage form of glucose in humans and other vertebrates and is composed of glucose monomers. Glycogen is similar to starch but is more highly branched and is typically stored in liver and muscle cells in animals. The process of breaking down glycogen to release glucose when blood glucose levels decrease is known as glycogenolysis. On the other hand, plants use starch as their storage form of glucose, which consists of two types of molecules: amylose and amylopectin.
Glycogen metabolism is crucial for maintaining energy levels and plays a vital role in the homeostasis of blood glucose levels in humans. Unlike glucose, glycogen can be stored with much less water, making it an efficient form of energy storage. In contrast, plants also store energy using cellulose, which provides structural support to the cell, and starch, which is used for energy storage and is less branched than glycogen.
