GCU BIO-205 Exam 1 Questions With Complete Solutions
3 domains of organisms Correct Answers Bacteria, Archaea,
Eukarya
Acidophiles pH Correct Answers below 5.5
Action of antibiotics on plasma membrane Correct Answers
Aerobic Incubation Correct Answers incubated in air. grows
best in tubes or flasks and shaken
aerobic vs anaerobic respiration Correct Answers Aerobic =
with Oxygen
Anaerobic = without Oxygen (Lactic acid is byproduct)
aerotolerant anaerobes Correct Answers can tolerate oxygen
and grow in its presence even though they cannot use it to
harvest energy
Alkaliphiles pH Correct Answers above 8.5
allosteric regulation Correct Answers The binding of a
molecule to a protein that affects the function of the protein at a
different site.
anabolism vs catabolism Correct Answers anabolism (building
up) and catabolism (breaking down)
, Anaerobic incubation Correct Answers No oxygen present stip
is placed into container blue when oxygen present white when
oxygen absent
Animalcules Correct Answers First term used to describe
microorganisms
Anton van Leeuwenhoek Correct Answers Father of
microbiology
Created 1st magnifying glass

ATP synthase Correct Answers Large protein that uses energy
from H+ ions to bind ADP and a phosphate group together to
produce ATP
Bacillus Correct Answers rod
