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.
Effects of pH. Enzymes are affected by changes in pH. The most favorable pH value-the point where the enzyme is most active-is known as the optimum pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.pH is also a factor in the stability of enzymes.As with activity, for each enzyme there is also a region of pH optimal stability. In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction.H is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability. In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction.
