Enzymes And Their Properties: What is Enzymes? Enzymes are a major class of proteins. They are also called as biological catalysts (biocatalysts) because they speed up the rate of reaction in organisms. In our body, numerous biological reactions are occurring which are not possible without enzymes. The enzymes have been defined as the simple or combined proteins acting as specific catalysts. They are soluble colloidal molecules produced by living cells. All enzymes are globular proteins. They have a complex 3’D’ structure. They can bind with the substrate molecule to a part of their surface. The enzymes do not change the … Continue reading Enzymes And Their Properties
