Gram+3. Gram –4. Cell Wall5. ArchaeaCurrent LectureWhy do antibiotics work? Why do they kill bacteria and not us?Targets of antibiotics:- Cell wallgram + or gram – shows differences in cell wallGram-- More complex- Porinouter membrane- Thin peptidoglycan- Cell membrane- Negative charge makes it harder to dehydrateGram+- Thick peptiologlycan cell membranePeriplasmThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Function: hydrolytic enzymes that degrade viruses- Binding proteins that help in cell transport- ReceptorsCell wall less forms- Widespread- Usually live in isotonic environments (water is not trying to go in or out)- Pheiomorphic or pleomorphic- Sterois- special lipid that helps give strength- Intracellular parasites Archaea- thermoplasma species- Found in piles- pH 1-2- 45*-59*C- Rigid membrane- Hydroskeleton formed by
