Verified step by step guidance1
Begin by understanding the role of hormones in the body. Hormones are chemical messengers that regulate various physiological processes, including metabolism, growth, and mood.
Identify the hormones listed in the problem: Insulin, Adrenaline, Thyroxine (T4), and Cortisol. Each of these hormones has distinct functions in the body.
Focus on Thyroxine (T4). Thyroxine is a hormone produced by the thyroid gland. It plays a crucial role in regulating the body's metabolic rate, which is the rate at which the body converts food into energy.
Consider the function of Thyroxine (T4) in metabolism. It increases the basal metabolic rate, affects protein synthesis, and influences the body's sensitivity to other hormones.
Compare Thyroxine (T4) with the other hormones listed. Insulin regulates blood glucose levels, Adrenaline prepares the body for 'fight or flight' responses, and Cortisol is involved in stress response and metabolism regulation. Thyroxine is specifically known for its role in controlling the metabolic rate.
