Question

Please answer all... Thank you!

(11 pts) 104) Identify the modes of action with the general antibiotic/chemotherapeutic categories. Only one answer is correct per agent Aminoglycosides Select One Antifungal Select One antibiotics Cephalosporins Select One Chloramphenicol Select One Erythromycin Select One Isonicotinic acid Select One hydrazide (Isoniazide) Nalidixic acid Select One Penicillins Select One Polypeptides Select One Sulfonamides Select One Tetracyclines Select One

Options: block specific metabolic reactions (competitive analogs), deterioration of a cell membrane (perhaps concomitant with some cell wall damage), inhibit cell synthesis, inhibits DNA synthesis, interfere with protein synthesis

Answer 1

•Aminoglycosides: Interfere with protein synthesis

•Antifungal antibiotics: Deterioration of a cell membrane (perhaps concomitant with some cell wall damage)

•Cephalosporins: Inhibit cell wall synthesis

•Chloramphenicol: Interfere with protein synthesis

•Erythromycin: Interfere with protein synthesis

•Isonicotinic acid hydrazide (isoniazide): Inhibit cell wall synthesis

•Nalidixic acid: Inhibits DNA synthesis

•Penicillin: Inhibit cell wall synthesis

•Polypeptides: Inhibits DNA synthesis

•Sulfonamides: Block specific metabolic reactions

•Tetracyclines: Interfere with protein synthesis
