Detailed explanation-1: -Insulin travels via the bloodstream to its target organs when it activates glucose uptake and thereby lowers plasma glucose. As a result, glucose uptake by the -cell is reduced, decreasing glucose metabolism, reactivating KATP channels and switching off insulin secretion.
Detailed explanation-2: -A spike in insulin signals the liver that a person’s blood glucose level is also high, causing the liver to absorb glucose and change it into glycogen. When blood sugar levels drop, glucagon instructs the liver to convert the glycogen back to glucose, causing a person’s blood sugar levels to return to normal.
Detailed explanation-3: -Insulin is normally secreted by the beta cells (a type of islet cell) of the pancreas. The stimulus for insulin secretion is a high blood glucose-it’s as simple as that. Although there is always a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises.
Detailed explanation-4: -Glucose induces insulin secretion by both triggering (i.e. involving closure of the KATP channels) and amplifying (i.e. post KATP channel closure) effects.
