Enzymes A and B catalyse the same reaction , but Km for A is 0.000006mol/l and for B is 0.003 mol/l.If both enzymes have the same Vmax and if the activity of both enzymes is measured for substrate concentration of 0.003 mol/l , the relation of V(of enzymeA):V(of enzymeB) is aprox a. 1:1 b. 2:1 c. 20:1 d. 1000:1
