Biology 121 Exam 1 Questions With Complete Solutions
1 ATP Correct Answers 4 H+ needed to make _______
1.8 billion years ago Correct Answers when did eukaryotes first
appear?
a Correct Answers without
Absorption Correct Answers grow on or near food and suck up
nutrition from it
activation energy Correct Answers the initial investment of
energy for starting a reaction, the energy required to contort the
reactant molecules so the bonds can break
activator Correct Answers binding of this to a regulatory site
stabilizes the shape that has functional active sites
active site Correct Answers the groove where catalysis occurs,
where the substrate binds to the enzyme
aerobic respiration Correct Answers catabolic, most efficient
pathway, oxygen is consumed along with organic fuel
Alcohol fermentation Correct Answers pyruvate is converted to
ethanol in two steps, done with NADH and makes 2 ATP per 2
pyruvate, only glycolysis, releases CO2
,allosteric regulation Correct Answers any case in which a
protein's function at one site is affected by the binding of a
regulatory molecule to a separate site
Amniotes Correct Answers tetrapods with a terrestrially adapted
egg
anabolic pathway Correct Answers consume energy to build
complex molecules from simpler ones, biosynthetic pathway
Annelida Correct Answers segmented worms
anology Correct Answers similarity due to convergent evolution
Arthropods Correct Answers A group of organisms that have
jointed appendages, an exoskeleton, bilateral symmetry, and
reproduce sexually; insects, arachnids, millipedes and
cenitpedes, and crustaceans
ATP Correct Answers ΔG is -7.3 KJ/mol
ATP hydrolysis Correct Answers catabolic, releases energy,
exergonic
ATP synthase Correct Answers enzyme that makes ATP from
ADP and inorganic phosphate, occurs in the inner membrane of
the mitochondria
ATP synthesis Correct Answers anabolic, requires energy,
endergonic
, Bacilli Correct Answers Rod shaped bacteria
bilateral symmetry Correct Answers Body plan in which only a
single, imaginary line can divide the body into two equal halves.
Biofilm Correct Answers surface coating colonies, secrete
signaling molecules to recruit nearby cells to make colony
growmo
blastic Correct Answers multi layered (ex triploblastic)
Blastula Correct Answers multicellular hollow ball
Brachiopods Correct Answers look like mollusks with crown of
cilia called lophophore
capsule Correct Answers A sticky layer that surrounds the cell,
lets prokaryotes stick to others or substrate, protects against
dehydration and host's immune system
catabolic pathway Correct Answers releases energy by breaking
down complex molecules into simpler compounds
cellular respiration Correct Answers Includes both aerobic and
anaerobic processes
cellular respiration equation Correct Answers C6H12O6 + 6O2
--> 6CO2 + 6H2O + ATP
change in free energy Correct Answers ∆G= Gfinal-Ginitial
