Gluconeogenesis & Cori Cycle Flashcards
liver can MAKE glucose in
gluconeogenesis
Gluconeogenesis is an_____ pathway
anabolic
Gluconeogenesis means
“sweet, new beginning”
Gluconeogenesis occurs in the …
cytoplasm
NEED GLUCONEOGENESIS FOR
HIGH ENERGY DEMAND IN MUSCLES OR STARVATION/SLEEP
Why is Energy Needed to Make Gluconeogenesis Go?
the opposite thermodynamic direction of glycolysis. “Up Hill” reaction
Gluconeogenesis is NOT
the reversal of Glycolysis
Gluconeogenesis Starts with
Pyruvate Carboxylase
Oxaloacetate is Transported Out of the Matrix as
Malate
Oxaloacetate is Converted to
PEP (High Energy) via PEP Carboxylase
PEP is Converted to
3-Phosphoglycerate
Phosphoglycerate Kinase Makes
1,3-BPG…in reverse
Fructose 1,6-bisphosphate is
Dephosphorylated
Glucose 6-phosphate is
Dephosphorylated to Glucose in the ER in the Liver
In Cori Cycle, Pyruvate is Reduced to
Lactate in Hard-Working (Anaerobic) Muscles
