WebGlucose stimulates insulin secretion from beta-cells but suppresses the release of glucagon, a hormone that raises blood glucose, from alpha-cells. The mechanism by … WebInsulin and C-peptide are stored in secretory vesicles which upon stimulation by glucose and other secretagogues, are released at equimolar concentration [58]. Following secretion, insulin and the C-peptide pass through the liver. In contrast to insulin, the C-peptide has a longer half-life (30–35 min) [57]. phoenix nursing homes hiring cnaWebInsulin is released in response to high blood glucose concentrations.
