Given the vmax value from problem 2, how would you design an experiment to test the active enzyme concentration in each new lot of enzyme that your company received from the supplier. assume that there is a model substrate, like pnpp from your lab experiment, available that can make use of a simple spectrophotometer absorbance measurement. (1 mark) b) given the vmax value from problem 2, how would you design an experiment to get the km values for both water and substrate, which the supplier does not provide.
