WebThe protein I have chosen, and will discuss in further detail, is insulin. Insulin is a hormone produced by the Beta cells, which are located in the pancreas, in clusters, known as the islets of Langerhans. It regulates blood sugar levels, however in diabetes there is a deficiency in production of this essential hormone. WebInsulin is secreted at a basal level for normal function of different cells. However, in response to high blood glucose levels, a series of signal transduction steps are initiated, resulting in the release of a large amount (or bolus) …
