Lab #5 Blood Glucose

When blood glucose levels rise, blood levels of glucagon will

decrease

Insulin causes blood glucose levels to

decrease

When blood glucose levels rise, blood levels of insulin

increase

Which of the following causes insulin secretion to decrease?

low blood glucose levels

Maintenance of blood glucose is performed by endocrine cells of

the pancreas

Glucagon causes blood glucose levels to

increase

Glucagon does not stimulate

glycogenesis

Ketones are made from

fatty acids

Insulin stimulates

glycogenesis

Immediately after a carbohydrate-rich meal, blood glucose levels will

increase

During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.

The symptoms of diabetes mellitus include high plasma glucose levels and ketoacidosis (blood pH decreases due to increasing levels of ketones). Explain how diabetes causes these symptoms.
