Verified step by step guidance

Step 1: Understand the absorptive state. The absorptive state occurs after eating, when nutrients from food are being absorbed into the bloodstream. During this time, the body focuses on storing energy and building reserves.

Step 2: Identify the role of insulin. Insulin is a hormone produced by the pancreas that plays a key role in regulating blood glucose levels. It promotes the uptake of glucose by cells, encourages glycogen synthesis in the liver, and facilitates fat storage.

Step 3: Compare the roles of other hormones listed. Glucagon, cortisol, and epinephrine are primarily involved in the post-absorptive state or stress responses, where they help mobilize energy reserves rather than store them.

Step 4: Recognize that insulin is the primary hormone responsible for directing the events of the absorptive state. It ensures that glucose is stored as glycogen, fats are stored in adipose tissue, and proteins are synthesized.

Step 5: Conclude that insulin is the correct answer because it orchestrates the storage and utilization of nutrients during the absorptive state, unlike the other hormones listed.
