• Liver is an insulin-guided organ. Its behavior changes depending on the level of the hormone insulin in the body. After eating, blood glucose level rise, which in people without diabetes triggers the pancreas to release insulin into the blood.
• Insulin is the signal for the body to absorb glucose from the blood. Most cells just use the glucose to supply them with energy. But the liver has a special job when it comes to glucose.
• When levels of glucose (and consequently glucose) are high in the blood, the liver responds to the insulin by absorbing glucose. It packages the sugar into bundles called glycogen.
• These glucose granules fill up liver cells, so the liver is like a warehouse for excess glucose. When glucose level drop, insulin production falls too.
• The storage of insulin in the blood is the signal that the liver needs to liquidate assets, sending its glucose stores back into the blood to keep the body well fed between meals and overnight.
