Key Terms — Do Not Confuse Them

Glucose: A simple sugar used in respiration
Glycogen: Storage form of glucose (in liver/muscles)
Glucagon: Hormone that RAISES blood glucose
Insulin: Hormone that LOWERS blood glucose

Remember: Insulin lets glucose IN to cells. Glucagon Gets glucose Out of storage!

Quick Recall Flashcards

What does insulin do when blood glucose is too high?

Insulin is released by the pancreas. It causes body cells to take up glucose from the blood, and causes the liver to convert excess glucose into glycogen for storage. Blood glucose falls.

What is glycogen and where is it stored?

Glycogen is the storage form of glucose. It is stored in the liver and in muscle cells. The liver can convert glycogen back to glucose when blood glucose falls too low.
