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.
Why enzyme activity is affected by pH. by Bhav Patel Â· October 10, 2014. Why enzyme activity is affected by pH. A pH is the measure of the concentration of hydrogen ions, H+ with their values ranging from 1 -14. pH 7 is said to be neutral, any value below this is said to be acidic and values above are alkaline.y doing this, it interferes with the binding of the substrate to the active site and it therefore changes the rate of activity of the enzyme â the rate of an enzyme controlled reaction). Every enzyme has their own optimum pHs; the pH where the rate of the enzyme controlled reaction is at its highest.
