How does insulin facilitate the entry of glucose in a cell?

Insulin:

1. Insulin is an anabolic peptide or protein hormone.
2. It is secreted by the Beta cells of islets of Langerhans, located in the endocrine pancreas.
3. Insulin functions in regulating the glucose level in the body.
4. Insulin facilitates the entry of glucose into the liver, skeletal muscle cells, and fat cells for the blood.
5. The entry of glucose into these cells is a function of insulin.
6. There are certain receptors present on the surface of these cells to which the insulin binds, this causes the molecules of GLUT4 to arrive at the surface of the cell.
7. GLUT is a glucose transport component that allows the cells to take in the glucose.
