Detailed explanation-1: -The pancreatic -cell plays a key role in glucose homeostasis by secreting insulin, the only hormone capable of lowering the blood glucose concentration.
Detailed explanation-2: -When blood glucose levels rise, beta cells in the pancreas normally make the hormone insulin. Insulin triggers cells throughout the body to take up sugar from the blood.
Detailed explanation-3: -The key role of the beta cells is to produce and secrete insulin in a tightly regulated manner, to maintain circulating glucose concentrations in the (narrow) physiological range (Cavaghan and Polonsky, 2005; Henquin, 2005; Poitout et al., 2015).
Detailed explanation-4: -The beta cells secrete insulin to facilitate glucose uptake into glucose recipient organs (mainly the muscle, brain, liver, and adipose tissue). Obesity is a key risk factor for type 2 diabetes as it desensitizes glucose recipient organs to the action of insulin.
Detailed explanation-5: -Beta cells are the producers of the only blood glucose-lowering hormone in the body: insulin.
