Hormones

Question 1

Hormones

Answer 1

Compounds released by cells and transported by blood to affect targets

Question 2

Where are Insulin and Glucagon produced?

Answer 2

Pancreas, in the Islets of Langerhans

Question 3

Alpha cells

Answer 3

Secrete glucagon which increases blood glucose

Question 4

Beta Cells

Answer 4

Secrete insulin which decreases blood glucose

Question 5

Insulin

Answer 5

Directs body to use and store energy molecules coming in from digestion

Question 6

Glucagon

Answer 6

Directs body to breakdown glycogen and fat to provide energy

Question 7

What can cause Glucagon to release?

Answer 7

Fasting, exercise, and also stressors like surgery or infection

Question 8

What is insulins role in control of glucose levels?

Answer 8

Hi concentration glucose detected by beta cells stimulates insulin secretion by beta cells down the bloodstream and stimulates glucose facilitated transport into muscle and fat and storage in liver and that lowers concentration glucose in the blood (lowers glucose level)

Question 9

Negative feedback

Answer 9

normal levels of glucose turn down production of insulin

Question 10

What is glucagons role in control of glucose levels?

Answer 10

Low concentration of glucose in blood detected by alpha cells increases glucagon secretion by alpha cells which moves through the bloodstream into the liver stimulating membrane receptors that are activated by glycogen phosphorylates that break down liver glycogen and release glucose into the blood (raises glucose level)
