Hi Deepa,
the transition times are metrics that reflect how fast each of the
variables is turning over in the steady state.
the definition is that it is the concentration of the species divided by
the flux that crosses it (ie the sum of all positive fluxes, or
alternatively the absolute value of the sum of all negative fluxes).
This has units of time.
large transition times mean that the corresponding species changes
slowly (so it will react slowly to perturbations)
small transition times mean that the corresponding species changes fast
(so it will react quickly to perturbations)
After a perturbation you should expect the species with the smallest
transtion times to be the first approaching a steady state, and the ones
that have the largest to be the last to approach the steady state.
In your results, NAD and d-glucose are the slowest of the species,
while phosphoenol and 1,3-bisphosphoglycerate 2,6-bisphosphate are the
fastest species.
