The enzyme, fumarase, has the following kinetic constants: S+E= ESP+E k-₁ where k₁ 10° M-¹ s¹ = k₁=4.4 x 104 s-¹ k₂= 10³ S-1 a. What is the value of the Michaelis constant for this enzyme? b. At an enzyme concentration of 106 M, what will be the initial rate of product formation at a substrate concentration of 10-³ M?
