E = enzyme, S = substrate, I = inhibitor, P = product and A = activator Rate constants (k's) for the forward reactions are: K1, K2, k3, K4, k5, k6, k7, and k8 Rate constants (k's) for the reverse reactions are: k-1, k-3, K.4, k.6, and k.7 Write the enzyme balance for this mechanism. How many total equations will result from applying the RAPID EQUILIBRIUM ASSUMPTION? Using any concentrations of species in the mechanism and any of the rate constants (k's), write ONE of the equations that would result from applying the QUASI STEADY STATE ASSUMPTION.

Substrates and reactive groups in an enzyme’s active site must be precisely aligned in order for a productive reaction to occur. Why, then, is some conformational flexibility also a requirement for catalysis? 2. Some plants contain compounds that inhibit serine proteases. It has been hypothesized that these compounds protect the plant from proteolytic enzymes of insects and microorganisms that would damage the plant. Tofu, or bean curd, possesses these compounds. Manufacturers of tofu treat it to eliminate serine protease inhibitors. Why is this treatment necessary?
