An Enzyme Catalyzes a Reaction at a Velocity of 20 $\mu$

question 49

Short Answer

An enzyme catalyzes a reaction at a velocity of 20 $\mu$ mol/min when the concentration of substrate (S) is 0.01 M. The K_m for this substrate is 1 × 10^-5 M. Assuming that Michaelis-Menten kinetics are followed, what will the reaction velocity be when the concentration of S is (a) 1 × 10^-5 M and (b) 1 × 10^-6 M?
