Activation energycorrect answers The amount of energy that reactants must absorb before a chemical
reaction will start; also called free energy of activation.
Active sitecorrect answers The specific portion of an enzyme that binds the substrate by means of
multiple weak interactions and that forms the pocket in which catalysis occurs.
Allosteric regulationcorrect answers The binding of a regulatory molecule to a protein at one site that
affects the function of the protein at a different site.
Anabolic pathwaycorrect answers A metabolic pathway that consumes energy to synthesize a complex
molecule from simpler compounds.
ATPcorrect answers An adenine-containing nucleoside triphosphate that releases free energy when its
phosphate bonds are hydrolyzed. This energy is used to drive endergonic reactions in cells.
Bioenergeticscorrect answers (1) The overall flow and transformation of energy in an organism. (2) The
study of how energy flows through organisms.
Catabolic pathwaycorrect answers A metabolic pathway that releases energy by breaking down complex
molecules to simpler compounds.
Catalystcorrect answers A chemical agent that increases the rate of a reaction without being consumed
by the reaction.
Chemical energycorrect answers Energy available in molecules for release in a chemical reaction; a form
of potential energy.
Coenzymecorrect answers An organic molecule serving as a cofactor. Most vitamins function as
coenzymes in metabolic reactions.
Cofactorcorrect answers Any nonprotein molecule or ion that is required for the proper functioning of
an enzyme. Cofactors can be permanently bound to the active site or may bind loosely with the
substrate during catalysis.
Competitive inhibitorcorrect answers A substance that reduces the activity of an enzyme by entering the
active site in place of the substrate whose structure it mimics.
Cooperativitycorrect answers A kind of allosteric regulation whereby a shape change in one subunit of a
protein caused by substrate binding is transmitted to all the others, facilitating binding of subsequent
substrate molecules.
Endergonic reactioncorrect answers A nonspontaneous chemical reaction, in which free energy is
absorbed from the surroundings.
