questions with complete solutions
Drugs - correct answer ✔✔Chemicals that affect physiology in any manner.
ex; Caffeine, alcohol, tobacco.
Chemotherapeutic agents - correct answer ✔✔Drugs that act against diseases.
ex; insulin, anticancer drugs, antimicrobial agents.
Antimicrobial agents - correct answer ✔✔Drugs that treat infections.
Paul Ehrlich - correct answer ✔✔German scientist.
Proposed "chemotherapy", chemicals selectively kill pathogens having little/no
effect on patient.
"Magic bullets" arsenic compounds that would bind to receptors on germs and kill
them, ignoring the host cells because they lack receptor molecules.
Alexander Fleming - correct answer ✔✔British bacteriologist.
First person to discover and document antibiotics.
Antibacterial action of penicillin released from Penicillium mold, which creates
zone where bacteria don't grow.
, Gerhard Domagk - correct answer ✔✔German chemist.
Discovered sulfanilamide, the first practical antimicrobial agent that treated a

Antibiotics current definition - correct answer ✔✔Antibacterial agent including
synthetic compounds, excluding agents with antiviral and antifungal activity.
Semisynthetic antimicrobials - correct answer ✔✔Chemically altered antibiotics
that are more effective, longer lasting, or easier to administer than naturally
occurring ones.
Most antimicrobials are either natural or semisynthetic.
Synthetic drugs - correct answer ✔✔Antimicrobials that are completely
synthesized in a lab.
Key to successful chemotherapy - correct answer ✔✔Selective toxicity
Selective toxicity - correct answer ✔✔An effective antimicrobial agent must be
more toxic to a pathogen than to the pathogen's host.
Possible because of differences in structure or metabolism between pathogen and
its host.
