General enzyme-catalyzed reaction
WebAn 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. When two substrates and one enzyme are involved, the … WebReactions catalyzed by enzymes are among the most effective, selective, and 'green' processes available today. The advantages of using biocatalysts include their high degree of regio- and stereo-specificity, versatility, and high …
