- v0 = Vmax + [s] / Km x [s], where the variables are v0 and [s] and the parameters are Km and vmax
- v0 = Vmax x [s] / Km + [s], where the variables are v0 and the parameters are [s], Km and vmax
- v0 = Vmax x [s] / Km + [s], where the variables are v0 and [s] and the parameters are Km and vmax
- v0 = Vmax x [s] / Km + [s], where the variables are v0 and Km and the parameters are Km, [s] and vmax
- v0 = Vmax x [s] / Km x [s], where the variables are v0 and [s] and the parameters are Km and vmax

- NADH is a common chemical
- quartz cuvettes can be used

## 5. By definition enzymes

- always catalyse irreversible reactions
- act as biological catalysts
- act as chemical catalysts
- convert ligands to products
