Which organ stores glycogen?

Which organ stores glycogen?

• A. Liver
• B. Pancreas
• C. Gallbladder
• D. Small intestine

Answer: (A)

Glycogen is the storage form of glucose, and the liver is the main organ that stores it to help regulate blood sugar. After eating, the liver converts excess glucose into glycogen (a process called glycogenesis) and stores it for later use. When blood glucose drops between meals, the liver breaks down glycogen back into glucose (glycogenolysis) and releases it into the bloodstream to keep tissues supplied, especially the brain. Among the options, the liver uniquely serves this glycogen storage and glucose-regulating role. The pancreas handles hormones and digestive enzymes, the gallbladder stores bile, and the small intestine digests and absorbs nutrients rather than storing glycogen.
