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.
Write down your hypothesis about the effect of the range of pH on enzyme activity: Set up 7 test tubes with 40 drops of a different buffered pH solution in each. Add 10 drops of potato extract to each and stir. Then add 10 drops of 1% catechol to each and stir.e will be using the enzyme catecholase (or catechol oxidase) that is common in plants; it is present in the freshly squeezed potato juice that has been provided. The substrates of catecholase are catechol and oxygen. The substrates react with one another within the active site of the enzyme.
