Which of the following hormones is produced in the pancreas?

Insulin is the hormone produced in the pancreas, specifically in the beta cells of the islets of Langerhans. It plays a crucial role in regulating blood glucose levels by facilitating the uptake of glucose into cells, aiding in its conversion to energy, and storing excess glucose as glycogen in the liver. This regulation is vital for maintaining homeostasis, as consistently high or low glucose levels can lead to health issues such as diabetes.

The other hormones mentioned are produced in different glands. Adrenaline (also known as epinephrine) is produced in the adrenal glands, which are located on top of the kidneys, and it is involved in the body's fight-or-flight response. Cortisol, another hormone produced by the adrenal glands, plays a role in metabolism and the immune response. Thyroxine is produced in the thyroid gland and is involved in regulating metabolism and energy levels in the body. This differentiation of hormone production is essential for understanding the role that each hormone plays in the body's overall functioning.
