Carbohydrate Metabolism - (German) Flashcards
1
Q
G-6-Phosphatase is only found where?
A
In the liver -(converts G6P into glucose)
2
Q
What activates Glycogenesis? Glycogenolysis?
A
Glycogenis: Insulin
Glycogenolysis: Epinephrine & Glucagon
3
Q
What enzyme breaks of G1P off of a glycogen molecule?
A
Glycogen phosphorylase
4
Q
What are the input costs of Gluconeogenisi?
A
4 ATP
2 GTP
2 NADH
5
Q
What are the 2 allosteric modulators for Glycogenolysis?
A
GLucose & Insulin
6
Q
T or F: Gluconeogenesis can occur in ALL Cells?
A
TRUE
7
Q
What are the major fates of glucose?
A
- Pyruvate
- ECM
- Ribose-5-phosphate
- Glycogen Storage
8
Q
When plasma sugar is high, what is released?
A
Insulin - to promote glycogenesis
9
Q
When plasma sugar is low, what is released?
A
Glucagon - to promote glycogenolysis and the eventually - glycolysis
