Enzymes are often described as following the two-step mechanism: E+S⇌ES(fast) ES→E+P(slow) Where E = enzyme, S = substrate, ES = enzyme-substrate complex and P = product. Question: Molecules that can bind to the active site of an enzyme but are not converted into product are called enzyme inhibitors.Write an additional elementary step to add into the preceding mechanism to account for the reaction of E with I, an inhibitor. Express your answer as a chemical equation.

8. Enzymes often exhibit pH-dependent activity due to protonation/deprotonation of key amino acids. A general schematic is shown in i) for a pH-dependent enzyme, in which the "active" pathway requires EH and ESH. The constants ka, kz, kcat are the usual rate constants for the Michaelis-Menten reaction scheme, and the dissociation constants KEI, KESI, KE2, Kesz are defined as shown in ii). a. Derive a M-M rate equation for the pH-dependent scheme, below. To do so: 1) express total enzyme...
