If we plot V i as a function of [S], following observations will be made: At low [S], the initial velocity,V i, rises linearly with increasing [S]. When [S] increases, V i settle down (rectangular hyperbolais formed).Michaelis-Menten Enzyme Kinetics. Enzymes are highly specific catalysts for biochemical reactions, with each enzyme showing a selectivity for a single reactant, or substrate.Many enzyme-substrate reactions follow a simple mechanism that consists of the initial formation of an enzyme-substrate complex, \(ES\), which subsequently decomposes to form product, releasing the enzyme to react again. Keq = [P]/ [S] Enzymes cannot change Keq, they just increase onset of equilibrium. - enzymes are unchanged. - they lower the activation energy by helping transition state. Describe a zero order reaction rate. Rate is independent of [S] but proportional to [E] or another factor. Describe first order reaction rates. Enzyme Kinetics by Isothermal Titration Calorimetry.
