The term scalawag was originally used as far back as the 1840s to describe a farm animal of little value; it later came to refer to a worthless person. For opponents of Reconstruction, scalawags were even lower on the scale of humanity than carpetbaggers, as they were viewed as traitors to the South.
Enzymes speed up reactions by lowering the activation energy of the reaction concerned. The enzyme creates a lower energy pathway than if the enzyme wasn't there. For example, â¦ hydrogen peroxide, H2O2, decomposes when it gets warmer to H2O(l) and O2(g).
1 Higher reaction rates. 2  Reactions that take advantage of an enzymes ability to speed up the reaction often have rates which are 10 6 to 10 12 times faster than the corresponding uncatalyzed reactions. 3  The reaction rate with enzymes are still several times greater than those using standard chemical agents as catalysts.
