Chapter 6-11 Flashcards
(26 cards)
Potential energy
Stored energy
Energy
The capacity to bring about movement against an opposing force
Kinetic energy
Energy in motion
Thermodynamic
The study of energy
First law of thermodynamics
Energy is never created or destroyed but is only transformed
Second law of thermodynamics
In every energy transaction some energy will be lost to the most disordered from of energy heat
Entropy
Measures the amount of disorder in system,the greater the entropy the greater the disorder
Exergonic reaction ( breaking down)
The reaction in which the starting set of a molecule ( the reactants) contains more energy than the final set of molecules ( the product) breaking down
Endergonic reactions ( buildup)
Reaction in which the product contain more energy than the reaction
Coupled Reaction
A chemical reaction in which an exergonic reaction powers and endergonic reaction.
ATP
The most important energy transfer molecule in living things
After glycolysis where is the energy that was originally in glucose
2ATP
2NADH
2 Pyrunic acid molecules
The ultimate electron acceptor at the end of the electron transport chain ETC is
Oxygen
Genomes consistent of
All the genetic information for that organism
Enzyme
A type of protein that accelerates the rate at which a chemical reaction take place in an organism
Substance
An enzyme helps transform through chemical reaction
Metabolic pathways
A series or reaction is undertaken in sequence each facilitated by its own enzyme
Metabolism
The sum of all the chemical reaction that a cell or large organism carries out
Activation energy
The energy required to initiate a chemical reaction
Catalysts
Substance that retain their original chemical composition while bringing about a change in a substrate.
Active site
The portion of an enzyme that binds with a substrate
Coenzymes
Molecules other than amino acids that facilitate the work of enzyme by binding with them
Competitive inhibition
A reduction in the activity of an enzyme by mean of a compound other than the enzyme’s usual substrate binding with the enzyme in its active site.
Allosteric regulation
A molecule binds with the enzyme at a site other than its active site
