Global parameters

The Vmax value in the paper "Modeling cancer glycolysis" is given in  U \times \text{(mg total cellular protein)}^{-1} unit [1]. To homogenize the units it is then converted back to \frac{mM}{min} by multiplying  U \times \text{(mg total cellular protein)}^{-1} with 65 as the HeLa cell was incubated in  65 \frac{\text{mg protein}}{\text{mL cell volume}}.
