Blood glucose concentration

• What happens if blood glucose concentration falls too low?

  There won’t be enough glucose for tissue cells to respire
• After eating does our blood glucose concentration increase or decrease?

  Increase
• Which organ detects changes in blood glucose concentration?

  Pancreas
• Which hormone decreases blood glucose levels?

  Insulin
• What are the 2 main organs that insulin stimulates to absorb glucose from the blood?

  Muscle and liver.
• When glucose is absorbed by the liver for long term storage, what molecule is it converted to?

  Glycogen.
• How glucagon works :

  1.when blood glucose levels fall too low, it’s detected by the pancreas.

  2.this causes the pancreas to release the hormone glucagon into the bloodstream.

  3.this hormone then travels around the body, and binds mainly to cells in the liver.

  4.this stimulates those liver cells to break down their stored glycogen into glucose and release it into the blood.

  5.this extra glucose increases blood glucose levels back up to normal.
