Question

Insulin is produced by?

1) Islets of Langerhans in the pancreas.
2) walls of the intestines.
3) acinar cells of the pancreas.
4) red blood cells to help maintain glucose levels.

Answer 1

Insulin is produced by the beta cells within the Islets of Langerhans in the pancreas, helping to regulate blood glucose levels by facilitating glucose uptake by cells. The correct option is 1) Islets of Langerhans in the pancreas.

Step-by-step explanation:

Insulin is a hormone produced by the pancreas, and more specifically, it is produced by the beta cells found in the Islets of Langerhans. These clusters of endocrine cells release insulin when blood glucose levels rise, such as after a meal, facilitating the uptake of glucose by the body's cells and promoting glycogen synthesis. The regulation of blood glucose levels is critical, and insulin works along with glucagon, another hormone produced by the alpha cells of the same islets, to maintain homeostasis.
