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).
KINETICS IN BIOCHEMISTRY: THE ACTION OF CATALYSTS. Virtually all of the chemical reactions that occur in our bodies are catalyzed by enzymes. Without enzymes, these reactions would occur too slowly to be biologically relevant. It is important to understand what an enzyme can do, and what it cannot do.What enzymes can do, and do very well, is speed up reactions.INETICS IN BIOCHEMISTRY: THE ACTION OF CATALYSTS.
