Consider a description of an enzymatic reaction pathway that begins with the binding of substrate S to enzyme E and ends with the release of product P from the enzyme. E+S →ES → EP E+P Under many circumstances, KM = [E] [S] / [ES] What proportion of enzyme molecules are bound to substrate when [S] = KM? Why? Recall that when [S] = KM, the reaction rate is Vmax/2. Does your answer to Part A make sense in light of...

Enzymes are often described as following a two-step mechanism: Where E = enzyme, S = substrate, ES = enzyme-substrate complex, and P = product. Write the balanced equation for the overall reaction. Identify and intermediates in the reaction mechanism. Derive an expression for the rate law.
