Pathways include the complete glycolytic pathway, the citric acid cycle and Electron Transport System .   Amino acid biosynthesis and the production of purines are complete, however of the pyrimidines, the cytidine production pathway lacks the final cytidine triphosphate synthetase, hence, cytidine cannot be synthesized.  In order for C. diphtheriaeto to colonize the host, it needs this pyrimidine base.  What is this nutrient requirement called, and from where does the bacterium obtain it?

What is the mechanism that makes Bacteria resistant to Beta-lactams

Looking at these antibiotics, Polymyxin, sulfamethoxazole, streptomycin, tetracycline, and rifampin.  Why would  P.aeruginosa be resistant to sulfamethoxazole, streptomycin, tetracycline, and rifampin but suspectible to Polymyxin?

This is from micro biology. Which box goes under which category

Which metabolic pathways are involved in Covid 19 infections

Escherichia coli O157:H7 is a foodborne pathogen and can cause serious illness in humans by producing toxins that can severely damage the lining of intestines and kidneys. What are the oxygen requirements of coli? What result would you observe in the MTM agar deep test? Explain. Research on the growth requirements of this bacterium is required. What is the role of oxygen and cytochrome c oxidase in aerobic respiration? Why does the nitrate reduction tube turn red after the addition of zinc? Clostridium tetani is a common soil bacterium and causes tetanus. Would you expect tetani to possess the enzyme catalase? Explain. Research on the growth requirements of this bacterium is required.

Describe how the minimum inhibitory concentration of anantibacterial agent is determined.

Inorganic Nitrate (N03-)  contaminated the soil around their plant.   Scientists developed mechanisms for removing Nitrite (N02-)  from the soil, but have not found one for Nitrate (N03-).  Is there any types of bacteria that could metabolize Nitrate (N03-) to give rise to Nitrite (N02-)? Indicate ALL metabolic pathways that could be used  (aerobic respiration, anaerobic respiration, aerobic chemolithotrophy, and anaerobic chemolithotrophy) to carry out this reaction? Which of these reactions can oxidize or reduce inorganic materials
