Enzyme hydrolysis of glucose-6-sulfate occurs in a marine microorganism. The activity test is based on the rate at which glucose is metabolized. Its KM is 6.7 x 10-9 M and its Vmax is 300 nM min-1 in cell-free extract. Galactose-6-sulfate competes with the enzyme to inhibit it. When glucose-6-sulfate and galactose-6-sulfate are present at 2 x 10-5 M, the starting speed is 1.5 nM min-1. Take a look at the Ki for galactose-6-sulfate and figure out what it is.
