Review sheet for Exam III. I am supplying this review sheet to help you recall what we have discussed in class. The test questions will cover materials we discussed in class and assignments (study guides) you did for each topic. You are expected to use what you learn in class to solve problems or you may be asked to explain phenomena using principles you learn from class. The concepts I hope you should understand are provided in this review sheet. A, Bacteria. 1, the difference between Gram positive and Gram negative bacteria in terms of the cell wall structure. A gram positive bacteria will have a thick layer of peptidoglycan (a sugar-protein shell) that the stain can penetrate. A gram negative bacteria has an outer membrane covering a thin layer of peptidoglycan on the outside. The outer membrane prevents the initial stain from penetrating. Ester Linkages 2, You should understand the different mechanisms of penicillin and lysozyme in killing Gram positive and Gram negative bacteria. Penicillin: Most effective against gram positive because prevent synthesis of peptidoglycan. Lysozyme: Effective against gram negative and breaks down outer membrane. 3, Understand the different mechanisms antibiotic resistance in bacteria develops. Conjugation: Plasmid to plasmid through bridge (sex pili) Transformation: DNA is freely floating from dead cell and living cell picks it up Transduction: Delivery by phage 4, Understand how bacteria mate, why they mate. Think about antibiotic resistance development.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
