The action of enzymes is often described as following a two-step mechanism, named after the biochemists Michaelis and Menten, where in the first step the enzyme and the substrate form an intermediate complex, and in the second step the enzyme is released and the product is formed. Schematically, E + S ⇆ ES (fast) , k1 and k-1 are the rate constants for the direct and reverse reactions respectively. ES → E + P (slow), k2 is the rate constant...

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.

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.

4. The NOT-ALL-EQUAL 3SAT problem is defined as follows: Given a 3-CNF formula F, is there a truth assignment for the variables such that each clause has at least one true literal and at least one false literal? The NOT-ALL-EQUAL 3SAT problem is NP-complete. This question is about trying to reduce the NOT-ALL-EQUAL 3SAT problem to the MAX-CUT problem defined below to show the latter to be NP-complete. A cut in an undirected graph G=(V.E) is a partitioning of the...
