- The polysaccharide is produced and then stored as glycogen in the liver. Glycogen is transformed into glucose when the body needs energy, and then glucose is released into the blood to reach the target cell.
- A multibranched polymer of glucose is called glycogen.
- In both humans and animals, glucose is stored as glycogen.
- Mostly in the liver and muscles, glycogen is created and stored.
- The process of glycogenesis transforms any glucose that is not immediately consumed into glycogen for storage in the liver and muscles.

Understanding Glycogen Storage
Glycogen is a crucial polysaccharide that serves as a primary storage form of glucose in the body. It is primarily synthesized and stored in the liver and muscle cells. Here’s a detailed explanation of why glycogen is the correct answer:
1. Role of Glycogen
- Glycogen acts as an energy reserve that can be quickly mobilized to meet sudden needs for glucose.
- It is particularly important during fasting or intense physical activities when blood glucose levels must be maintained.
2. Synthesis of Glycogen
- Glycogen is synthesized through a process called glycogenesis, where glucose molecules are linked together.
- This process occurs in the liver and muscle cells, with the liver playing a vital role in regulating blood glucose levels.
3. Storage in Liver Cells
- The liver can store a considerable amount of glycogen, which can be converted back into glucose when the body requires energy.
- When blood glucose levels drop, the liver breaks down glycogen through glycogenolysis, releasing glucose into the bloodstream.
4. Other Options Explained
- **Galactose (a)**: A simple sugar found in milk but not stored in the liver as glycogen.
- **Lactose (b)**: A disaccharide sugar composed of glucose and galactose, not synthesized or stored in the liver.
- **Arabinose (d)**: A pentose sugar found in plant polysaccharides, not relevant to liver storage.
In conclusion, glycogen is uniquely made and stored in liver cells, making option 'C' the correct choice. Understanding glycogen's function and synthesis is essential for grasping how the body manages energy resources effectively.
