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.
Increasing further temperature damages the active sites and changes their shapes. Substrates can no longer fit into the active sites. At temperatures higher than 60 degrees Celsius enzymes are basically completely denatured. Thus pH and temperature affect the enzyme activity to a great extent as seen above. They are highly sensitive to temperatures as well as pHs.
