This is part 2 to the meet a pathogen essay you already wrote. Instructions below: Metabolism, Growth, and Genetics Text Resources for this paper: Chapters 8, 9, 10, and 11 Nutrition List the different types of microorganisms based on 1) their source of carbon; 2) the energy sources for different types of organisms, and 3) the type of energy metabolism in heterotrophs (e.g., oxygen respiration). Explain with more detail the classifications of your selected pathogen based on the three parameters listed here. Metabolism Describe how enzymes work. Include the terms catalyst, activation energy, substrates, bonding, and products. Explain how bacteria obtain energy during fermentation and aerobic respiration. Describe the advantages and disadvantages of both fermentation and aerobic respiration to the bacterial pathogen. Use the number of ATP generated in your comparison. Indicate the type of process or processes your selected bacterial pathogen use to get energy. (SLO 8) Bacterial growth Briefly describe bacterial growth and binary fission. Define exponential growth and indicate the conditions necessary for exponential growth. List some of the environmental factors that affect microbial growth. Find possible environmental factors that your bacterium may encounter and describe them. Genetics Briefly describe the structure of DNA and RNA. Explain the role of DNA and RNA in the formation of proteins; use the terms replication, transсrіption and translation in your explanation. Find information on the DNA sequencing of the chromosome of your selected bacterium to complete the table below, and compare your bacterial chromosome to the human chromosome one, the largest of the 23 pairs of chromosomes in the human genome. Define or describe the characteristics shown in the first column. Characteristics Selected Bacterial Pathogen Chromosome Human Chromosome One Size, mm. (bp x 0.34) 85 Base Pairs 248,956,422 Encoding segments or genes 2,058 Non-encoding segments or pseudogenes 1220 Structural RNAs 200 From Wikipedia, Human Genome. Last updated 04/20/2018 bp ＝ base pairs Critical thinking question What is the role of genetic mutations on the development of antibiotic resistance by some bacterial species? Explain. Are some strains of your selected bacterium resistant to some antibiotics? Illustrations Find appropriate graphs or images to illustrate two or three of the processes included in this report. For example, you could add a figure showing enzyme activation and catalysis work, and an illustration of the DNA and RNA molecules to show their structure and base pairs.
