1- The increase in glucose (sugar) level in the blood after digestion stimulates insulin secretion from the pancreas.
2- Insulin enables glucose to be converted into energy by the cells, transferring the increased energy to the liver and muscle cells and storing it as glycogen.
3- After the stores are filled, liver cells convert excess glucose into fat and leave it to the bloodstream. Fat cells collect and store the increased blood fat. (fattening begins)
4- When the level of glucose in the blood drops, glucagon hormone is secreted from the pancreas into the blood.
5- Glucagon stimulates the liver cells to break down and release glycogen. Blood sugar is balanced.
6- Blood glucagon levels vary depending on the food consumed.
