Range of flux values used for the generation of random fluxes

Flux	Range
TCA Cycle	1
Gluconeogenesis	0.4–0.7
Glycogenolysis	0.1–1.7
Pyruvate carboxylase (y)	0.5–2.5
Cori cyclea	0.3–2.0
Label scrambling in muscle due to pentose pathway	0.1–1.0
Label scrambling in liver due to fumarase	1.0–4.0
Tracer infusion rate	0.05–0.3
Plasma lactate dilution	0.7–1.5

^aCori cycle refers to flux from plasma glucose to plasma lactate.
