Lesson 2 Definitons Flashcards
Gibbs Free energy
amount of energy available to do work
activation energy
energy required to begin reaction
binding energy
energy released during reaction
AMP
adenosine MONOphosphate (as opposed to DI and TRIphosphate)
ADP
ingredient of DNA
ATP
short term energy storage, coenzyme (energy currency) generated by coenzyme Q10
Chelate
a compound containing a ligand (typically organic) bonded to a central metal atom at two or more points
active site
where enzyme/substrate interaction occurs
apoenzyme
inactive enzyme lacking it’s cofactor
allosteric control
a molecule binds to enzyme and changes it’s physical shape, either activating or inhibiting enzyme
feedback inhibition
excess product binds to the enzyme and causes it to stop producing.
precursor
a substance from which a (usually more mature) substance is formed
ribozyme
nucleic acids (RNA) that act as both enzymes and information storage
proteome
complete set of proteins, different from genomes because they can change depending on the gene
ribonuclease
catalyzes the degradation of RNA into smaller parts, contains 124 amino acids
Genome
complete set of genes in an organism
allosteric site
site that allows molecules to effect enzymes
interactome
the whole set of molecular interactions in a given cell
