Question

Name the hormone that regulates the raise in blood sugar and mention the source of it.

Answer 1

Regulation of blood glucose is regulated by two hormones secreted by pancreases named as insulin which lower down the raised level of glucose and glucagon which increase the level of glucose when its fall in blood.

Complete answer:
The regulation of blood glucose level or sugar level is called glucose homeostasis. Which I maintained by two kinds of hormones which are secreted by pancreases into the bloodstream. Basically blood sugar is maintained by the negative feedback mechanism.
Glucagon is the hormone which is secreted by the alpha cells of pancreas, which is released into the bloodstream and travel to the liver, where it is bind to the glucagon receptors on the surface of the liver cells and excite, to break down the stored form of glucose called glycogen this process is called glycogenolysis. Thus cells release the glucose into the bloodstream and raise the level of glucose. This situation occurs when a person suffers from hypoglycemia (lower level of blood sugar).
Insulin is the hormone, which is secreted by the beta cells of islets of Langerhans of the pancreas. Insulin releases into the bloodstream and reaches to the liver, where it stimulates the liver to convert the blood sugar into the glycogen (stored form), this process is called glycogenesis. This process decreases the blood sugar level which is present in high levels which is not good for health. If high blood sugar level is not maintained then it will create hyperglycemic conditions. Diabetes mellitus Type 1 occurs due to insufficient or not present insulin.

Note:
Both hormones are necessary for the regulation of blood sugar level and both are released from the pancreas but different cells, insulin released by beta cells of islet of Langerhans while glucagon is released by alpha cells of pancreas.
