1major non carb precursors are
lactate, animal acids,and glycerol
2lactate enters gluconeogenesis what step
step 1 with pyruvate
3amino acids enter gluconeogenesis at which step
step 1 with pyruvate and step 2 with oxaloacetate
4glycerol enters gluconeogenesis at which step?
step 7 with dihydroxaceacetone phosphate
5the irreversible step of glycolysis are
bypasssed in gluconeogenesis
6oxaloacetate cannot be transported across mitochondrial membrane so what happens
it is reduced to malate transported to cytosol and then oxidized back to oxaloacetate during gluconeogenesis
7when glucose is abundant
glycolysis will predominate
8when glucose is scarce
gluconeogenesis will predominante
9futile cycle
when two metabolic pathways run simultaneously in opposite directions and have no overall effect other than to dissipate energy in the form of heat
10describe the Cori cycle
lactate formed by active muscle is converted into glucose by the liver. it shifts part of metabolic burden of active muscle to the liver
