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).
Share to: To catalyze a reaction means to speed it up. Enzymes speed up reactions by bringing together the chemicals that are needed to react, rather than waiting for them to bump intoâ¦ each other by chance. If it weren't for enzymes, most reactions in living cells would happen too slowly to be useful. 7 people found this useful.
