How do enzymes affect the chemical reaction

WebWhat effect do enzymes have on activation energy Why are they useful in chemical reactions? Enzymes facilitate chemical reactions by lowering the activation energy required for the reaction to occur. In effect, enzymes can take a reaction to completion but through a different path. This quality of lowering activation energy makes enzymes ... WebEnzymes are biological catalysts, and therefore not consumed or altered by the reactions they catalyze. They repeatedly bind substrate, convert, and release product, for as long as substrate molecules are available and thermodynamic conditions are favorable (ΔG is negative; the product/substrate ratio is lower than the equilibrium ratio).

WebEnzymes catalyze a reaction by lowering the activation energy, which is the amount of energy needed to begin a chemical reaction. All chemical reactions need activation energy to get started. Activation energy is needed to speed up the motion of molecules to increase the frequency and force with which they collide. WebEnzymes perform the critical task of lowering a reaction's activation energy —that is, the amount of energy that must be put in for the reaction to begin.
