Fusion of an intracellular vesicle with the plasma membrane🔍

In a pancreatic B cell glucose enters via GLUT 2 and enters glycolysis. This causes the increased concentration of ATP in the cell causes the closure of ATP sensitive K+ channels. When this happens the cells becomes depolarized allowing Voltage gated Ca2+ channels to be open. The Ca2+ allows for exocytosis of insulin into the blood vessel.

Hence the answer here... Fusion of an intracellular vesicle with the plasma membrane.
