What Is Enzyme Catalysis?

Enzymatic catalysis can be regarded as a kind of catalytic reaction between homogeneous and heterogeneous catalytic reactions. It can be regarded as that the reactant forms an intermediate compound with the enzyme, or it can be regarded as that the reactant is first adsorbed on the surface of the enzyme and then the reaction is performed.

Enzyme catalysis

Right!

Enzymatic catalysis can be seen as a difference between homogeneous and non-homogeneous

Enzyme catalytic principle

In nature, about a third of enzymes require metal ions as cofactors or activators. Some metal-containing enzymes contain metal ions, especially transition metal ions such as iron, molybdenum, copper, and zinc, which are firmly combined with the protein part to form the active site of the enzyme. This enzyme is called a metalloenzyme, such as a nitrogen-fixing enzyme that fixes free nitrogen molecules in the atmosphere to ammonia, containing molybdenum and iron; a copper oxidase that oxidizes a substrate and reduces oxygen molecules to water; and makes H2 (or H + ) Iron and sulfur-containing hydrogenases converted to H + (or H2); a class of molybdenum-containing oxidoreductases (such as nitrate reductase, purine dehydrogenase, xanthine oxidase, aldehyde oxidase, sulfite oxidase And formate dehydrogenase). The macromolecules of these enzymes contain clusters of atoms composed of several metal atoms as active centers to activate and activate substrate molecules. The way in which they activate substrate complexation and the principle of coupling electrons and energy through ligands are similar to the corresponding homogeneous and heterogeneous catalysis processes.

Enzyme-catalyzed development

Understanding the various enzyme action mechanisms ingeniously designed during the evolution of nature in the hundreds of millions of years will not only uncover the mystery of the biocatalytic process, but also lay a scientific foundation for humans to use some of these principles to research and develop new and efficient catalysts, and Drive the development of the marginal disciplines of catalysis--photoassisted catalysis, electrocatalysis, and photocatalysis.
