Protein protein the mechanism of enzymatic action: an enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface). the combination formed by an enzyme and its substrates is called the enzyme–substrate complex. Mechanism of enzyme action: enzymes neither initiate the reaction nor affect the equilibrium ratio of reactants and products. rather, enzymes accelerate the rate of reaction 10 8 to 10 12 times in both directions to attain the equilibrium position. activation energy:. Haider alshawi m.sc. medical lab tech biochemistry lecture : 8 enzymes mechanism of action of enzymes 1 lock: key model of enzyme action implies that the active site of the enzyme is complementary in shape to that of its substrate, i.e. the shape of the enzyme molecule and the substrate molecule should fit each other like a lock and key 2. The specificity of these enzymes’ action depends on the nature of the given apoenzyme. conditions of enzyme action. enzyme action depends on a number of factors, primarily temperature and the reaction of the medium (ph). the temperature conducive to optimum enzymatic activity is generally in the range of 40°–50°c. 1) co 2 h 2 o ← carbonic anhydrase h 2 co 3 {\displaystyle {\ce {co2{} h2o< [{\text{carbonic anhydrase}}]h2co3}}} (in lungs ; low co 2 concentration) (2) the rate of a reaction is dependent on the activation energy needed to form the transition state which then decays into products. enzymes increase reaction rates by lowering the energy of the transition state. first, binding forms a low.

Mechanisms of enzyme action. kinetics of an uncatalyzed chemical reaction: s s* p “reaction coordinate” free energy, Δg ea is “activation energy”. Mechanism of enzyme action: arrhenius first pointed out that, all the molecules in a given population do not have the same kinetic energy some molecules are energy poor and other are energy rich. higher is the energy barrier the grater is the inactiveness of reaction. Mechanism of enzyme action. in most chemical reactions, an energy barrier exists that must be overcome for the reaction to occur. this barrier prevents complex molecules such as proteins and nucleic acids from spontaneously degrading, and so is necessary for the preservation of life.
