BI-234 - LECTURE CHAPTER 10 EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS LATEST UPDATE
To delay the infection so the immune system can eliminate it
What is the primary job of antibiotics?
the ability of a drug to target and kill harmful microorganisms without damaging
the host's cells
What is selective toxicity?
Cell membrane, cell wall synthesis, protein synthesis, nucleic acid synthesis,
metabolic pathways
What are the 5 targets of antimicrobial action?
Because they are easier to invent. Bacteria aren't using our cells, like viruses do.
Bacterial cells are very different from human cells, the drugs target the
differences between human and bacterial cells.
Why are most antimicrobial drugs antibacterials?
From a naturally produced fungi called penicillium chrysogenum
Where was penicillin discovered?
Penicillin, cephalosporins, vancomycin, and bacitracin.
Which antibiotics inhibit cell wall synthesis?
A class of antibiotics that contains a beta-lactam ring in their chemical structure
that blocks the peptide cross bridges in the cell wall, which causes them to burst
from osmotic pressure. Used only when the bacteria is trying to actively replicate.
What are beta-lactams?
