GI Part 6- 4 Flashcards
What is the production of glucose from non-sugar molecules such as AA, lactate, and glycerol?
Glucongenesis
Gluconeogenesis is _____ a “reverse glycolysis”
NOT
What process requires enzymes localized in the mitochondria and cytosol?
Gluconeogenesis
What are the 2 important tissues for gluconeogenesis?
Liver and kidney
What does glycerol enter the gluconeogenesis as?
Glycerol phosphate
What does lactate enter the gluconeogenesis as?
Pyruvate
What does AA enter the gluconeogenesis as AFTER the TCA cycle?
Oxaloacetate
What is a mechanism to store glycogen in order to mobilize glucose in absence of a dietary source?
Glycogenesis
What are the 2 main stores in the body for glucogenesis?
Skeletal muscle and liver
What is the process by which glucose is mobilized from glycogen granules in order to be sent into the blood and other tissues?
Glycogenolysis
What is needed for the pentose phosphate cycle?
Hexose
Where does the pentose phosphate cycle occur?
Cytosol
What cycle does NOT consume or generate ATP
But it does produce a major portion of NADPH in the body and ribose 5-phosphate?
Pentose phosphate pathway
The pentose pathways cycle:
_______ is formed and is used for:
FA synthesis
Steroid synthesis
Drug metabolism
Glutathione reduction
Generation of superoxidase phagocytes by NADPH oxidase
NADPH
Where do the short and medium chain FAs get into to reach the liver?
Portal circulation
