Aresearcher purifies a mutant version of the glucokinase enzyme. she combines the purified glucokinase with glucose and atp to produce glucose 6-phosphate. she records the initial velocity (v) of glucose 6-phosphate production at various substrate concentrations ([s]). she determines a michaelis-menten constant (km) of 8.5 mm for the mutant enzyme.
