(3) Describe insulin secretion from the pancreas. Where is it produced? When is it secreted? insulin is produced in the pancreas. it secretes from the pancreas when the brain gets a signal that the body is full. (well fed.) it secretes after meals essentially. insulin receptors open and glucsoe is taken into cells.

(4) What is the role of insulin? insulin allows the cells to take in glucose

(5) What is diabetes mellitus? the insulin is not produced or someone develops a resistance towards insulin.

(6) How does a glucose tolerance test assist in the diagnosis of diabetes? an glucose tolerance test shows how quickly glucose leaves the blood. if it doesn't leave the blood quickly then the test might indicate that the insulin receptors or insulin production is not working correctly. perhaps.. the patient has developed a resistance to insulin

(7) What causes diabetes type 1? doesn't produce insulin.

(8) How is diabetes type 1 controlled? by injecting insulin into the body routinely

(9) What causes diabetes type 2? a resistance to insulin

(10) How is diabetes type 2 controlled? diet, excercise, medication
