Weathering and soil formation.
Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.
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.
