Verified step by step guidance

Step 1: Begin by understanding the role of each hormone listed in the options. Insulin, glucagon, adrenaline, and cortisol are all involved in regulating metabolism, but they have distinct functions.

Step 2: Recall that insulin is a hormone produced by the pancreas (specifically by beta cells in the islets of Langerhans) and is primarily responsible for lowering blood glucose levels by stimulating cells to absorb glucose, fatty acids, and amino acids.

Step 3: Compare insulin's function to glucagon, which is also produced by the pancreas but has the opposite effect—it raises blood glucose levels by stimulating glycogen breakdown in the liver.

Step 4: Consider adrenaline (epinephrine), which is secreted by the adrenal medulla and primarily functions to prepare the body for 'fight or flight' responses, increasing heart rate and mobilizing energy stores rather than directly stimulating nutrient absorption.

Step 5: Evaluate cortisol, a steroid hormone produced by the adrenal cortex, which helps regulate metabolism during stress by promoting gluconeogenesis and the breakdown of fats and proteins, but does not directly stimulate cells to absorb glucose, fatty acids, or amino acids.
