What is glycogenesis?

What is glycogenesis?

• A. The breakdown of glycogen into glucose.
• B. The production of glucose from amino acids.
• C. The conversion of glucose to fat.
• D. The process of converting excess glucose into glycogen for storage.

Answer: (D)

Glycogenesis is the process of converting excess glucose into glycogen for storage, mainly in the liver and skeletal muscle. When blood glucose is high, insulin signals the body to store glucose as glycogen. The glucose is first turned into UDP-glucose, then glycogen synthase links glucose units into long chains, with branching enzyme creating branches to form a compact storage molecule. This stored glycogen can later be broken back down to glucose when needed through glycogenolysis. In contrast, making glucose from amino acids is gluconeogenesis, and turning glucose into fat is lipogenesis, while breaking down glycogen is glycogenolysis.
