Answer:
When levels of blood sugar rise after a meal the insulin hormone is released and it causes the liver to convert more glucose into glycogen and increases glucose uptake by cells through GLUT4 transporter. This decreases glucose levels in the blood. In the absence of insulin or decreased sensitivity of insulin, there is deregulation of glucose metabolism in the body.
