The enzyme y catalyzes the elementary reaction
ab→a+b
an enzyme concentration of 1.0 μm y can convert a maximum of 0.5 μm ab to the productsa and b per second. note: since the concentrations of species in the cytoplasm of cells is small, the concentration unit of micromolar (μmor 10−6 m) is used for consistency with biochemical systems.
six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.
a) 0.2 um ab
b) 0.3um ab
c) 0.6 um ab
d) 0.4 um ab
e) 0.7um ab
f) 0.5 um ab
