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.

Taya2010 [7]

Answer:

primary; counter; Gram-positive; Gram-negative

Explanation:

The illustration is about the <u>Gram-staining procedure.</u>

<em>The procedure is used to distinguish between the bacteria that have a thick cell wall capable of retaining the color of a dye (Gram-positive) or otherwise (Gram-negative). </em>

A smear of the bacterium to be tested is heat-fixed to a clean glass slide after which a suitable primary stain is added, allowed to stay for a few seconds, and rinsed. A mordant is then added, rinsed before a counter-stain is added, and also rinsed. The slide is then allowed to drain off water and then viewed under the microscope using the oil immersion. Gram-positive bacteria will appear blue or purple, taking up the color of the stain while Gram-negative bacteria will appear red under the microscope.
