BIO 250 EXAM 1 - MICROBIOLOGY - QUESTIONS AND
ANSWERS WITH VERIFIED SOLUTIONS 100% CORRECT
acidophiles - correct answer- high acidic conditions required for
growth
active transport - correct answer- requires energy, ATP, uses
proteins to move molecules
Animalae - correct answer- are not green, move
antimicrobial drugs - correct answer- produced using
microorganisms, to inhibit growth of other microbes
antiseptics - correct answer- Chemical agents applied to body tissues
to destroy or inhibit vegetative pathogens
asepsis - correct answer- Practices that prevent introduction of
infectious organisms into tissue
Assimilation - correct answer- Process of importing and
incorporation of molecules by living cells; Ability of cell to bring in
certain molecules
, Auxotrophs - correct answer- - Organisms require important
molecular precursors , one or more nutrients in order to grow
B-Lactamases - correct answer- Enzymes produced by bacteria that
cleave β-lactams;
This enzyme cleaves/breaks down the beta lactams which allows the
bacteria to become resistant to the drug
B-Lactams - correct answer- binds with enzyme in bacteria - breaks
down linkage between NAG and NAMs
baccilus - correct answer- rod shaped
barophiles - correct answer- organisms that live in high pressure
environments, deep ocean
bright-field - correct answer- image formed when light passes
through the specimen; object dark against a light background
capsules - correct answer- thick layer of polysaccharides, protection
from host immune response, prevents dessication, biofilm production
co transport - correct answer- two or more substances moved by
transporter
