Question

Is insulin an enzyme?

Answer 1

Hint: Hormones are chemical messengers which are secreted via the ductless glands referred to as endocrine glands. Hormones coordinate different bodily and mental activities of the body and hold a steady- state. Thyroxine, insulin, adrenalin are some of the examples of hormones.

Complete answer:
Since the endocrine gland does no longer have duct, its secretion is without delay poured into the bloodstream which incorporates them to organs and tissues of the body to exert their functions. There are distinct types of endocrine glands such as pituitary glands, thyroid glands, pancreas located at special components in the body.

The pancreas is an organ of an alimentary canal. It is a leaf-like organ placed just beneath the stomach. The pancreas is composed of two essential tissues such as the acini and islets of Langerhans. The endocrine part of the pancreas is the islets of Langerhans. The islets of Langerhans are composed of alpha cells and beta cells which secrete hormones glucagon and insulin respectively immediately into the bloodstream.

Insulin regulates glucose concentrations in the blood. If the blood glucose attention is too high, the pancreas produces the hormone insulin, this motivates glucose to pass from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen to be used later.

So, insulin is a hormone and not an enzyme.

Note: The Acini tissue of pancreas is the exocrine section that releases pancreatic juice that includes digestive enzymes into the duodenum of the small intestine. In the closing digestion of carbohydrates, protein and fats occur in the duodenum. The enzymes include: Protein digesting enzymes trypsin and chymotrypsin. They break down protein into dipeptides and amino acids. Pancreatic amylase which digests starches into sugar.
