Explanation: 

Detailed explanation-1: -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-2: -Glucose induces insulin secretion by both triggering (i.e. involving closure of the KATP channels) and amplifying (i.e. post KATP channel closure) effects.
