Assignment 5: Compare aerobic respiration
1. Compare aerobic respiration, anaerobic respiration and
fermentation. How are the processes similar? How are they
different? How do these processes determine which environment
the organism can live in? (Key terms to use in answer: electron
transport chain, cytochrome, ATP, glucose, glycolysis, obligate
aerobe, facultative anaerobe, microaerophile, obligate anaerobe,
oxidase, catalase, peroxidase, CO2, organic acids and alcohols,
alternative substrates (other than glucose))
2. Using your knowledge of DNA recombination events to
complete the following:
A.Propose two ways in which antibiotic resistance may develop in
a bacterium
B.Describe how bacterial cells acquire the ability to produce
toxins (Use the following terminology in your answer:
recombination, DNA, horizontal gene transfer, conjugation,
transformation, transduction, pilus, F factor, transposable
elements, transposons, pathogenicity islands)
3. Discuss how a pathogen causes an infection. Include definitions

(caused by a living organism), and various stages of pathogenesis.
