Which process converts glucose to glycogen and is stimulated by insulin?

Which process converts glucose to glycogen and is stimulated by insulin?

• A. Glycolysis
• B. Glycogenesis
• C. Gluconeogenesis
• D. Lipogenesis

Answer: (B)

When insulin is present after a meal, glucose that’s in excess is stored in liver and muscle as glycogen. The process that builds glycogen from glucose is glycogenesis. Insulin activates the enzymes involved, especially glycogen synthase, to add glucose units to the growing glycogen molecule, so this pathway is directly about converting glucose into glycogen for storage. Glycolysis, by contrast, breaks down glucose to extract energy. Gluconeogenesis makes new glucose from non-carbohydrate sources, not from existing glucose being stored. Lipogenesis converts glucose-derived carbon into fat rather than into glycogen. So the scenario described—glucose turned into glycogen under insulin’s influence—points to glycogenesis.
