AND TRUE!
Activation energy - Answer: the amount of initial energy necessary for reactions to
occur
Active site - Answer: a specific region on the enzyme where the substrate binds
Allosteric inhibition - Answer: the mechanism for inhibiting enzyme action in which a
regulatory molecule binds to a second site (not the active site) and initiates a
conformation change in the active site, preventing binding with the substrate
Anabolic - Answer: describes the pathway that requires a net energy input to
synthesize complex molecules from simpler ones
Bioenergetics - Answer: the concept of energy flow through living systems
Catabolic - Answer: describes the pathway in which complex molecules are broken
down into simpler ones, yielding energy as an additional product of the reaction
Competitive inhibition - Answer: a general mechanism of enzyme activity regulation in
which a molecule other than the enzyme's substrate is able to bind the active site and
prevent the substrate itself from binding, thus inhibiting the overall rate of reaction for
the enzyme
Endergonic - Answer: describes a chemical reaction that results in products that store
more chemical potential energy than the reactants
Enzyme - Answer: a molecule that catalyzes a biochemical reaction

, Exergonic - Answer: describes a chemical reaction that results in products with less
chemical potential energy than the reactants, plus the release of free energy
Feedback inhibition - Answer: a mechanism of enzyme activity regulation in which the
product of a reaction or the final product of a series of sequential reactions inhibits an
enzyme for an earlier step in the reaction series
Heat energy - Answer: the energy transferred from one system to another that is not
work
Kinetic energy - Answer: the type of energy associated with objects in motion
Metabolism - Answer: all the chemical reactions that take place inside cells, including
those that use energy and those that release energy
Noncompetitive inhibition - Answer: a general mechanism of enzyme activity regulation
in which a regulatory molecule binds to a site other than the active site and prevents the
active site from binding the substrate; thus, the inhibitor molecule does not compete
with the substrate for the active site; allosteric inhibition is a form of noncompetitive
inhibition
Potential energy - Answer: the type of energy that refers to the potential to do work
Substrate - Answer: a molecule on which the enzyme acts
Thermodynamics - Answer: the science of the relationships between heat, energy, and
work
Which of the following is not an example of an energy transformation?
A. Heating up dinner in a microwave
