BCH 369 chapter 7 Test withQuestions Solved 100% Correct |
Latest Update
Kinetics - Answer The study of chemical reaction rates
v - Answer velocity (rate) of reaction
ES complex - Answer The noncovalent complex that forms between an enzyme
and its substrate in the first step of an enzyme-catalyzed reaction.
saturation - Answer The state in which all of a macromolecule's ligand-binding
sites are occupied by ligand.
unimolecular reaction - Answer A reaction involving one molecule
rate equation - Answer A mathematical expression for the time-dependent
progress of a reaction as a function of reactant concentration.
rate constant (k) - Answer The proportionality constant between the velocity of
a chemical reaction and the concentration(s) of the reactant(s).
, First order reaction - Answer A reaction whose rate is proportional to the
concentration of a single reactant.
bimolecular reaction - Answer A reaction involving two molecules, which may
be identical or different.
second-order reaction - Answer A reaction whose rate is proportional to the
square of the concentration of one reactant or to the product of the
concentrations of two reactants.
steady state - Answer A set of conditions under which the formation and
degradation of individual components are balanced such that the system does
not change over time.
Michaelis constant (Km) - Answer For an enzyme that follows the michaelis-
menton model, Km = (k-1 +K2)/k1; Km is equal to the substrate concentration at
which the reaction velocity is half-maximal.
V0 - Answer Initial velocity of an enzymatic reaction
Vmax - Answer Maximal velocity of an enzymatic reaction
Michaelis-Menten equation - Answer A mathematical expression that describes
the activity of an enzyme in terms of the substrate concentration ([S]), the
enzyme's maximal velocity (Vmax), and its michaelis constant (Km): Vo = Vmax
[S]/(Km + [S]).
