Males are heavier than females; males weigh 794 to 1,323 pounds (360 to 600 kilograms), while females weigh 595 to 882 pounds (270 to 400 kg), according to the National Museum of Natural History. Moose have short tails, a hump on their shoulders and large ears that can rotate to give them stereophonic hearing.
The Effect of pH on Enzyme Activity. pH is a measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration, the lower the pH. Most. enzymes function efficiently over a narrow pH range. A change in pH. above or below this range reduces the rate of enzyme reaction. considerably.
Effect of temperature and pH on enzyme activity. Enzymes are basically the proteins which speed up the rate of reactions in living cells. These catalysts are made by the cells in very small amounts which are not consumed during a chemical reaction.
