Energy
The ability to do work.
Potential Energy
Having the capacity to do work.
Kinetic Energy
The energy of motion.
First Law of Thermodynamics
It states that energy can be neither created or destroyed.
Second Law of Thermodynamics
It states that disorder in a closed physical system tends to increase.
Entropy
This is the measure of disorder of a physical system.
Reactants
These are the molecules that are entering a chemical reaction.
Activation Energy
This is the energy that pushes chemical reaction to get going.
Exergonic Reaction
This is when the products contain less energy than the reactants. The extra energy is released into nearby molecules
Catabolic Reactions
Reactions that release energy by breaking down complex molecules into simpler molecules.
Endergonic Reaction
The product contains more energy in its chemical bonds than in its reactants.
Anabolic Reaction
Reactions that use energy to build complex molecules from simpler molecules.
Coupled Reactions
These are reactions that occur in conjunction with one another.
Metobolic Pathways
These are chains of chemical reactions that move, store, carry, and release energy in living systems.
Enzymes
These are special proteins that regulate the reactions in metabolic pathways.
Catalyst
This is a substance that increases the rate of a chemical reaction, but it is not chemically charged by the reaction.
Induced fit
This is when the binding of a substrate causes the shape of the enzyme to change, allowing a better fit.
Substrates
These are the substances on which enzymes act.
Active Sites
These are the locations on the enzymes where a reaction is catalyzed.
Activator
This activates a enzyme.
Inhibitor
This turns off an enzyme.
Negative Feedback
When the end product feeds information back to the first enzyme in the pathway, shutting down the pathway where there is excess end product.
Cofactors
These are non protein parts of an enzyme.
Coenzymes
These are cofactors that are organic molecules.
ATP
This is the energy currency of a cell that can captures energy from a exergonic reaction, carry this energy, and then “spend” it when needed.
Ribose
This is a five ring sugar that is one subunit of ATP.
Adenine
This is a double ring molecule that makes up ATP.
Triposphate Group
These are three phosphate groups linked in a chain, a subunit of ATP.
Adenosine
This is the ribose and the adenine linked together.
Phosphorylation
This is when ATP transfers chemical energy as it transfers its terminal phosphate group.
ADP
This is the molecule that remains after phosphorylation.
