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).
â¢ Enzymes are proteins that act as catalysts. Catalysts increase the rate of a chemical reaction without being consume by the reaction. Enzymes are not altered during a reaction and therefore they can be reused again and again.â¢ An enzyme speeds up a reaction by lowing the reactionâs activation energy.ll reactions require some energy to get started (activation energy). Enzymes lower the activation energy they do not provide activation energy. All chemical reactions require activation energy (Ea). Without enzymes reaction in cells would be slow and take a very long time.â¢ Enzymes are specific for certain reactions.
