Do proteins control chemical reactions
WebAbstract. Proteins occupy a unique status among the constituents of biological matter by virtue of their relatively large size and complex, multifaceted, and multireactive structures. These properties give them superb characteristics for functioning in biological systems in many different ways, but these characteristics also make many proteins ... WebLike other catalysts, enzymes are not reactants in the reactions they control. They help the reactants interact but are not used up in the reactions. Instead, they may be used over and over again. Unlike other catalysts, enzymes are usually highly specific for particular chemical reactions. They generally catalyze only one or a few types of ...
