Glucagon Pathway Diagram. High blood glucose low blood glucose the diagram shows the steps in the homeostasis pathway that occur when blood glucose levels fall. Glucose is phosphorylated to glycose 6 phosphate by the enzyme.
Overall directions of glycogenolysis and glyco genesis pathways are indicated with arrows located at the top and bottom portions of the diagram. Inhibited by glucagon epinephrine. They stimulate the gluconeogenesis by 3 mechanisms.
The process of formation of glycogen from glucose in the tissues is called glycogenesis.
The glucagon secreting alpha cells surround the insulin secreting beta cells which reflects the close relationship between the two hormones. Glucagon regulates the release of glucose from storage. Synthesis a precursor molecule proglucagon undergoes post translational processing to become a biologically active glucagon. Inhibited by glucagon epinephrine.
