julia-pushkina [17]

Answer:

Explanation:

a) Ph that is below or above the optimal range will result in enzyme activity loss.  if the pH changes above or below optimum range affects the charges that is present on the amino acid molecules. Amino acids presrnt in the active  site of enzymes that attracted each other may no longer continue to be attracted. Again, the shape of the active site of the enzyme changes due to the substrate binding will be affected. conclusively, we can say that the enzymes are denatured.

b) researchers are most likely to use a negative control when measuring the rate of reaction in the presence of each organisms. enolase is controlled  with no enzyme.

c) c) Since the C.aurantiacus grows best at 550C , we can say that the enzymes that they produce must be at this temperature and so they must be sensitive to this temperature ; hence they would show more activity at 550C temperature.
