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?

The pathway shown below is used by a fungus to create Arginine from a precursor starter molecule. A nonsense mutation occurs in the gene that encodes enzyme 2. This fungus is grown on media that only contains the precursor. Discuss the effects of this mutation on:(i) The function of Enzyme 2 (ii) The potential of the fungus to produce Ornithine
Examine the graph shown below of a liquid culture growth curve for S. pneumoniaegrowing in minimal broth containing both glucose and lactose in equal concentrations as a potential carbon source. Answer the following questions: a) Name the growth phases labelled as I, II and III, explain the observed pattern of growth at each of these stages in the curve b) Where would the concentration of cAMP be low and why? c) In what phase would β-galactosidase be high and why? d) What kind of overall growth pattern does this curve illustrate?
One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/

A series of auxotrophic mutants were isolated in Neurospora. Examination of fungi containing these mutations revealed that they grew on minimal medium to which various compounds (A, B, C, D) were added; growth responses to each of the four compounds are presented in the following table. Give the order of compounds A, B, C, and D in a biochemical pathway. Outline a biochemical pathway that includes these four compounds and indicate which step in the pathway is affected by each of the mutations.

Chlamydia are pathogenic bacteria that must be grown within a eukaryotic host cell. They rely on the host cell for many nutrients, including nucleotides, lipids, and amino acids. It is thus no surprise that when grown in co-culture with a host depleted of any of these metabolites, chlamydial growth declines. However, high levels of certain amino acids also inhibit chlamydial growth. Specifically, the amino acids leucine, isoleucine, methionine, and phenylalanine slow down the growth by inhibiting the amino acid transporter called BrnQ. On the other hand, if valine is present in the medium these amino acids have no effect on BrnQ. Discuss how this might be possible
What is the name of the fungal toxin that inhibits RNA polymerase Il at 1 microgram/mL concentration? O Flavopiridol a-Amanitin O Triptolide DRB (5,6-Dichloro-1-ß-D- ribofuranosylbenzimidazole)
Bacteria that are obligate intracellular pathogens of humans are considered to be Autotrophs Heterotrophs Photosynthetic Hyperthermophiles Chemolithotrophs Which of the following statements best describes the pathogenesis of Clostridium botulinum? It elaborates an exotoxin that is a lecithinase that causes tissue necrosis. It elaborates a toxin that suppresses the release of inhibitory neurotransmitters. It produces a polysaccharide capsule that inhibits phagocytosis and contributes to invasion of the central nervous system. It elaborates a toxin that inhibits the release of acetylcholine at cholinergic synapses. It produces a leukotoxin that leads to abscess formation.
It was important for Lilly to understand how the bacteria were able to cause disease in patients. The mechanism of pathogenesis by M. tuberculosis starts in the lung alveoli. The cell wall of M. tuberculosis allows it to resist phagocytolysis by the alveolar macrophages, where they can multiply. They can then induce apoptosis in macrophages, which die, and the bacteria is free to infect other macrophages. As the cycle of infection slowly progresses, the body's response to the infection is to try to wall off the bacteria in granulomas (wall of immune cells, both dead and alive, surrounding the bacteria to restrict its spread). Eventually, the bacteria can escape the granuloma and infect other parts of the lung. Transmission of Mtb Initial infection and Granuloma cavitationy replication of Mtb in macrophages and dissemination of Mtb in the lung Infected macrophages Caseating granuloma Recruitment of Innate and adaptive immune cells Infected cells undergo necrosis resulting in the…

The synthesis of arginine by Nuerospora was determined by examining a number of mutant strains that were unable to synthesize the compound. Use the table of bacterial growth below to 1) determine the correct sequence of the synthesis pathway and 2) where in the synthesis pathway each mutation interrupts the synthesis. A “+" indicates growth. Nothing added to Succinate Ornithine added Strain Cirtulline Arginine Added added added growth medium Wild Mutant 1 Mutant 2 Mutant 3 Mutant 4
