BSC 1010C Chapter 8 Quiz Questions With Complete
Solutions
__________ includes all chemical reactions occuring with in a
cell. Correct Answers metabolism
__________ is the endergonic synthesis of molecules. Correct
Answers Anabolism
__________ is the exergonic breakdown of substrates. Correct
Answers catabolism
∆G = ∆H - T∆S Correct Answers Formula for free energy
6-8 Correct Answers Most enzymes work best between pH...
According to thesecond law of thermodynamics Correct
Answers the entropy of the universe is constantly increasing
active site Correct Answers The part of an enzyme or antibody
where the chemical reaction occurs.
Adenosine Triphosphate =3 phosphate groups + ribose +
adenine. Correct Answers ATP
All of the following statements regarding enzymes are true
Correct Answers Enzymes allow molecules to react in
metabolism by lowering activation energies.
Each type of enzyme has a uniquely shaped active site that gives
it specificity.
, Enzymes are very sensitive to environmental conditions that
influence the weak chemical bonds responsible for their three-
dimensional structure.
Some enzymes change shape when inhibitors bind to specific
allosteric receptor sites.
allosteric site Correct Answers specific binding site, not the
active site
shape of the enzyme is changed (can either stimulate or inhibit)
An unfavorable reaction that requires an input of energy in order
to proceed is __________. Correct Answers endergonic
anabolic pathway Correct Answers consume energy to build
complex molecules from simpler ones
Bioenergetics Correct Answers the study of how energy flows
through living organisms
catabolic pathway Correct Answers leads to the release of
energy by the breakdown of complex molecules to simpler
compounds
chemical energy Correct Answers Energy stored in chemical
bonds
coenzymes Correct Answers organic cofactors
cofactors Correct Answers nonprotein enzyme helpers
