Enzymes catalyst
WebEnzymes speed the rate of chemical reactions. A catalyst is a chemical involved in, but not consumed in, a chemical reaction. Enzymes are proteins that catalyze biochemical reactions by lowering the activation energy necessary to break the chemical bonds in reactants and form new chemical bonds in the products. WebEnzymes differ from ordinary chemical catalysts in several important respects: Enzymes are specific. Chemical catalysts can react with a variety of substrates. For example, …
