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).
Enzymes speed up the activation energy, minimum energy for a reaction to occur. It helps break down the different types of food we eat. For example, amylase helps break down carbohydrates. If enzymes were not avalible, we would basically starve to death because we are not getting the nutrients and energy required fast enough.
