Derive the rate laws for the following enzymatic using the pre-equilibrium to develop the rate laws. 2) Problem 7-15, p. 462. The hydrogen ion, 11+, binds with the enzyme (E‘) to activate it in the form of EH. H+ also binds with EH to deactivate it by forming EH2 M +13 E121 if; a gazes; '4‘ "'L—J'L [H‘izueanj EWVI-“JI’Br ‘ *lziflwl ‘ Emilia“ ens—4 an“.
