Q.1
Ans. (C) inhibition of cell wall synthesis, because bacteriostatic antibiotics inhibit their growth or reproduction. Therefore, this comes in bactericidal antibiotics because they kill bacteria by inhibiting cell wall synthesis.
All of the following methods of actions are bacteriostatic except: competitive inhibition with folic acid synthesis...
The following are antibiotics / antimicrobial mechanism of actions except: A) Inhibition of bacterial cell wall synthesis B) Inhibition of folate synthesis C) Inhibition of protein synthesis D) Inhibition of cortisol E) inhibition of synthesis of bacterial RNA and DNA Walter, a teenage patient is admitted to the hospital because of acetaminophen (Tylenol) overdose Overdoses of acetaminophen can precipitate life-threatening! abnormalities in which of the following organs? A) Lungs B) Liver c) Kidney D) Adrenal Glands A 13-month-old child recently...
Of the six categories of inhibition, (inhibition of cell wall synthesis, inhibition of protein synthesis, disruption of cytoplasmic membrane, inhibition of general metabolic pathway, inhibition of DNA or RNA synthesis, or inhibition of pathogens attachment or entry into host cell) which would be effective against viruses? Which would be practical to use?
here are the possible choices for the questions: Inhibition of cell wall synthesis. Inhibition of nucleic acid synthesis. Inhibition of protein synthesis. Inhibition of synthesis of essential metabolites. Injury to the plasma membrane. Here are the Questions: Which of the following best describes the mode of action of Penicillin? Which of the following best describes the mode of action of Sulfamethoxazole (a sulfa drug)? Which of the following best describes the mode of action of Tetracycline?
Fluoroquinolones, like Ciprofloxacin and Moxifloxacin. inhibit: protein synthesis. membrane cunction. DNA gyrase. enzyme function ax competitive inhibitofs. cell wall synthesis Modified Thayer Martin (MTM) is a supplemented chocolate agar made selective for pathogenic Neisseria(S. gororrhoeae & N meninguidu) by addition of: Vitamins Antibiotics High NaCI (7.5% salt) Low pH High pH What is not tnie of capnophiks? mammalian cells in culture have a requirement for increased carbon dioxide Neisseria Hemophilus all of the above arc true The TCA cycle produces
Label the image to review major targets of drugs acting on bacterial cells. Cephalosporins Protein synthesis inhibitors acting on ribosomes Cell membrane Sulfonamides (sulfa drugs) Cell wall inhibitors Penicillins Polymyxins Erythromycin Aminoglycosides Quinolones Folic acid synthesis DNA/RNA Rifampin
Sulfonamides Multiple Choice points C) block folic acid synthesis C) block peotidases that cross-link glyca molecules 0 damage cell membranes • interfere with longation of peptidoglycan O ach to the 305nbosomal subunit and runt protein synthes
List 3 mechanisms of antibiotic resistance. (3pts) -Antimetabolite action (inhibit nucleic acid synthesis or function) -Alteration of cell membranes (Inhibit cell wall synthesis of function) -Inhibition of protein synthesis For the 3 mechanisms, you listed above, list an example, and the antibiotic the organism has become resistant to. (6pts)
Please answer all... Thank you! 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 (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...
Briefly explain how each of the following mechanisms of action inhibits or kills bacteria and give examples of each: Inhibition of cell wall biosynthesis Inhibition of protein synthesis Inhibition of membrane function. Inhibition of nucleic acid synthesis Inhibition of metabolic pathways Inhibition of ATP synthase
Which of the following modes of action would not be fungicidal? a. inhibition of peptidoglycan synthesis b. inhibition of mitosis c. injury to the plasma membrane d. inhibition of nucleic acid synthesis e. All of the above are fungicidal modes of action
