Components of flux variability vs. oxygen uptake. Black circle represents Δ int , red circle represents Δ int + Δ ext and green circle represents Δ tot = Δ int + Δ ext + Δ gro . Δ gro is the only significant component of flux variability, Δ int and Δ ext having negligible values for all the range of oxygen uptakes studied.
