Regulation Of Glucose

Question 1

Why is glucose needed

Answer 1

It is needed by cells for respiration . It is important that the concentration of glucose in the blood is maintained at a constant level as too much or too little can lead to a coma and even death

Question 2

How is blood glucose regulated

Answer 2

The pancreas detects blood glucose concentrations then releases a hormone whic alters the amount of glucose in the blood

Question 3

What happens when the pancreas detects high blood sugar

Answer 3

The pancreas increases secretion of insulin and decrease secretion of glucagon. (Insulin is released by beta cells in the pancreas). Insulin causes muscle and liver cells to remove glucos from blood and store it as glycogen

Question 4

What happens when the pancreas detects low blood sugar

Answer 4

Pancreas decreases secretion of insulin and increases secretion of glucagon. (Glucagon I released by alpha cells) . Glucagon causes liver cells to convert glycogen to glucose and release it into the blood.
