Microbiology Lab Exam 5 Questions with
Correct Answers | Updated (100% Correct
Answers)
bactericidal Answer: ____________ antibiotics kill bacteria.
Ex: antiseptics and prescribed antibiotics
bacteriostatic Answer: ________________ antibiotics inhibit the growth
of bacteria and resulting in a reduced number of bacteria; they work
with the immune system to remove the microbes from the body.
-ex: sanitizers and disinfectants
mechanisms of action Answer: There are four ________________ ____

cell wall synthesis Answer: The first mechanism of action of
antibiotics is disruption of _____ _______ ___________:
an example of this mechanism is found with penicillin
protein synthesis Answer: The second mechanism of action of
antibiotics is disruption of _________ _____________: examples of this

nucleic acid synthesis Answer: The third mechanism of action for
antibiotics is disruption of __________ ________ ______________: examples
of this are quinolones (sinusitis, skin infections) and Rifampin
(leprosy, tuberculosis)
bacterial metabolism Answer: The fourth mechanism of action for
antibiotics is disruption of _______________ ______________:
example sulfonamides (eye infections, ear infections, bronchitis)
antibiotic Answer: A(n) ______________ is a substance that can kill or
inhibit the growth of bacteria.
horizontal gene transfer Answer: Antibiotic resistance can be spread
via _____________ ______ __________
broad Answer: __________- spectrum antibiotics target many different
