Select the compound that
contains the most energy:
ADP
ATP
P
Cannot determine using the information provided.
Enzymes are important biological catalysts because
they:
supply
the energy to initiate a biochemical reaction.
increase the free energy of a biochemical
reaction.
lower the entropy and enthalpy of a biochemical
reaction.
lower the activation energy of a biochemical
reaction.
Because
enzymes affect the speed of chemical reactions without being consumed, they
are referred to as:
hydrogen acceptors.
activation energy.
cytochromes
catalysts
Parts of the enzyme molecule that interact with a substrate are called:
cofactors.
induced-fit models.
reaction sites
active sites.
The substance on which an enzyme acts:
Product
ATP
Free Energy
Substrate
The reaction rate of an enzyme catalyzed chemical reaction would likely be affected by:
pH
Temperature
Substarate Concentration
All of the above
Which of the following statements regarding enzyme is TRUE?
Enzyme decrease the free energy change of a reaction.
Enzyme change the direction of chemical reactions.
Enzyme increase the rate of a reaction.
Enzymes are permanently altered by the reactions they catalyze.
The active site of an enzyme is the region that
binds allosteric regulators of the enzyme.
is involved in the catalytic reaction of the enzyme.
binds the products of the catalytic reaction.
is inhibited by the presence of a coenzyme or a cofactor.
