NettetThis effect on insulin secretion occurs in the fed state (10). Mechanisms explaining glucagon secretion are not as well understood as those of insulin secretion, although the direct effect of reduced glucose on cAMP (111), and the sodium-glucose cotransporters (SGLT) are thought to play a role in a-cell glucose transport (3). Nettet4. nov. 2024 · Insulin secretion is largely controlled at the level of the β-cell, and a single β-cell, taken out of the pancreas, retains the ability to release insulin in response to glucose. This process begins with glucose uptake and metabolism to ATP that subsequently closes ATP-sensitive K + -channels, resulting in membrane … charles ronald armento jr
