Two enzymes, A and B, use the same substrate. Enzyme A has a Km for its substrate of 15 uM and a Vmax of 240 qM/min. Enzyme B has a Km for its substrate of 120 mM and a Vmax of 800 M/min. If the substrate is present at 30 xM, which of the following is true? enzyme A will form more product since it operates better at lower substrate concentrations enzyme B will form more product since it is more effective at the conversion of enzyme substrate complex to product O the rate of product formation will be the same for both enzymes at all times the rate of product formation will be the same for both enzymes at only this substrate concentration 2 pts
