Glycogen Metabolism Flashcards
1
Q
What is glycogen?
A
polymer of glucose that is found in muscle and liver cells and is the main form of carbohydrate storage in animals
2
Q
What is glycogenesis?
A
formation of glycogen
3
Q
What is glycogenolysis?
A
the breakdown of glycogen
4
Q
Where does glycogenesis and glycogenolysis take place?
A
liver and skeletal muscle
5
Q
What is the purpose of breaking down glycogen in the liver?
A
maintain blood glucose levels during fasting states
6
Q
What is the purpose of breaking down glycogen in muscle cells?
A
supply skeletal muscle with glucose during exercise
7
Q
What exerts reciprocal control on glycogenesis and glycogenolysis?
A
insulin = stimulates glycogenesis
glucagon = stimulates glycogenolysis
