Side ASide B
The amount of energy that reactants must absorb before a chemical reaction will start.
activation energy
The specific portion of an enzyme that attaches to the substrate by means of weak chemical...
active site
A specific receptor site on some part of an enzyme molecule remote from the active site.
allosteric site
A metabolic pathway that synthesizes a complex molecule from simpler compounds.
anabolic pathway 
An adenine-containing nucleoside triphosphate that releases free energy when its phosphate...
ATP (adenosine triphosphate)
The study of how organisms manage their energy resources.
A metabolic pathway that releases energy by breaking down complex molecules to simpler compounds.
catabolic pathway
A chemical agent that changes the rate of a reaction without being consumed by the reaction.
Energy stored in the chemical bonds of molecules; a form of potential energy.
chemical energy
A substance that reduces the activity of an enzyme by entering the active site in place of...
competitive inhibitor
An interaction of the constituent subunits of a protein whereby a conformational change in...
A nonspontaneous chemical reaction in which free energy is absorbed from the surroundings.
endergonic reaction
In cellular metabolism, the use of energy released from an exergonic reaction to drive an endergonic...
energy coupling
The capacity to do work (to move matter against an opposing force).
A quantitative measure of disorder or randomness, symbolized by S
A spontaneous chemical reaction in which there is a net release of free energy.
exergonic reaction
A method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor...
feedback inhibition
The principle of conservation of energy. Energy can be transferred and transformed, but it...
first law of thermodynamics 
 The initial investment of energy necessary to start a chemical reaction; also...
free energy of activation
The portion of a system's energy that can perform work when temperature is uniform throughout...
The change in shape of the active site of an enzyme so that it binds more snugly to the substrate,...
induced fit 
The energy of motion, which is directly related to the speed of that motion. Moving matter...
kinetic energy
The totality of an organism's chemical reactions, consisting of catabolic and anabolic p
A substance that reduces the activity of an enzyme by binding to a location remote from the...
noncompetitive inhibitor
A molecule that has been the recipient of a phosphate group.
The energy stored by matter as a result of its location or spatial arrangement.
potential energy
The principle whereby every energy transfer or transformation increases the entropy of the...
second law of thermodynamics
The reactant on which an enzyme works.
(1) The study of energy transformations that occur in a collection of matter. See first...
 A globular protein that links into chains, two of which twist helically about each other,...
A eukaryotic cell organelle consisting of a 9 + 0 arrangement of microtubule triplets;...
basal body
The disruption of a cell and separation of its organelles by centrifugation.
cell fractionation
A protective layer external to the plasma membrane in plant cells, bacteria, fungi, and some...
cell wall
