Amylase: a sample enzyme
intro.bio.umb.eduEnzymes act as catalysts to increase the rates of chemical reactions, but they do not cause a reaction to occur that would not proceed spontaneously without the enzyme; that is, the reaction must have ΔG < 0. The reactions of metabolism would occur at extremely slow rates at normal body temperature and pH in the absence of enzymes. An
