Oh hai.

Some comments:

  • When you define steady state as meaning 99% of the cellulose is used up, it becomes unclear what it means for cellobiose or glucose.
  • You say Figure 3 shows cellobiose doesn't reach a steady state. But it goes to zero. If you mean it goes negative, you'll have to replot the graph to show that...
  • You say "Analysing steady state is important to find out whether a system accumulates excess mass or energy" - but we know it can't in reality, right, since this violates physics? Do you mean analysing steady state is important as a way of testing if the model is sane?
