In the insulin sequence, what is the fourth event after the third event?

• A. Glycogen is stored in the liver
• B. Glucose enters the bloodstream
• C. Glycogen converted to glucose by alpha cells
• D. Beta cells release insulin

Answer: (A)

When blood glucose rises, the key sequence starts with beta cells releasing insulin. Insulin then promotes glucose uptake and storage, with the liver converting excess glucose into glycogen (glycogenesis). Therefore, after the insulin release step, the next event is glycogen storage in the liver. The other options describe earlier steps or opposing actions: glucose entering the bloodstream is an initiating trigger, not a downstream event; beta cells releasing insulin is the trigger itself; glycogen conversion to glucose by alpha cells reflects glucagon’s action to raise blood sugar, not the insulin-driven storage sequence.
