During which metabolic state is glycogenesis primarily occurring?

• A. Post-absorptive state
• B. Absorptive state
• C. Fasting state
• D. Starvation state

Answer: (B)

Glycogenesis, the process of converting glucose into glycogen for storage, primarily occurs during the absorptive state. This metabolic state follows a meal when nutrients are plentiful, and insulin is released in response to rising blood glucose levels. Insulin promotes the uptake of glucose by cells, especially in the liver and muscle, where it can be stored as glycogen. The body is focused on using and storing energy from recently consumed carbohydrates, which provides a ready source of fuel for future needs. In contrast, during the post-absorptive, fasting, and starvation states, the body shifts towards utilizing stored energy. In these states, glycogenolysis (the breakdown of glycogen to glucose) becomes more prominent as the body needs to maintain blood glucose levels for essential functions, especially in the brain and red blood cells. These metabolic shifts reflect the body's adaptation to varying availability of nutrients, with glycogenesis being most active when there is a surplus of glucose.
