A type of tumor in the pancreas called a glucagonoma produces and releases excess glucagon into the blood. How would this affect the level of glucose in the blood? Would the overall effect on blood glucose differ from that of type I diabetes mellitus? Why or why not?

The excess production of glucagonoma release glucagon in the blood causing increase level of glucose in the blood which in turn causes type 1 diabetes mellitus.

Explanation:

The islet of Langerhans cells in pancreas contain alpha cell that are mainly responsible for increase glucose level in the blood by secreting glucagon hormone which prevents the fall of glucose level in the blood.The glucagon is stored in the liver and is released by the process of glycogenolysis.

Type 1 diabetes mellitus is a disease when the body fails to produce insulin hormone that is released by the beta cells of islet of Langerhans in pancreas,which acts to reduce the level of glucose in the blood and thus maintain an equilibrium of glucose in the body.

A glucagon is a one kind tumor of pancreas which released glucagon.it leads to rise glucose level in the blood.

Explanation:

Glucagonoma is a one kind neuroendocrine tumors.which occurs in alpha cell of the pancreas that leads to much production of glucagon.excessive production of glucagon leads to rise glucose level in the blood.

That does not differ from type one diabetes mellitus because it leads to rise blood sugar level.which is a symptoms of diabetes mellitus.

i really wish i could answer this question for you
