So the method by which cells use non carbohydrate materials such as glycerol to basically form glucose is known as gluconeogenesis. So glucagon stimulates the process of glycogenolysis as well as gluconeogenesis. Now, the overall result of a glucagon released by alpha cells is to basically raise glucose levels. And when the concentration of glucose increases to a certain amount, that can basically inhibit the release of glucagon into our blood. Now, glucagon is also inhibited by other proteins, by other enzymes, for example, insulin, as well as somatostatin. And we'll discuss these in just a moment.
