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.

2. hypothesize the best conditions (pH and temperature) under
which the enzyme chymotrypsin functions with an appropriate
reference. also, hypothesize what will occur in the presence of an
inhibitor and the type of inhibition.
