enzymes Flashcards
biological catalysts that speeds up chemical reaction by lowering activation energy
enzymes
suffix for enzymes
-ase
composition of enzyme
cofactor/coenzyme, apoenzyme, active site, and substrate
activates apoenzyme
coenzyme/cofactor
vitamin derivative
coenzyme
mineral derivative
cofactor
inactive for of enzyme
apoenzyme
apoenzyme and cofactor/coenzyme
holoenzyme
site where substrate will bind
active site
molecule which enzyme will act upon
substrate
according to this model, enzymes will only act upon a specific substrate
lock and key model
according to this, an enzyme molds itself to the shape of a molecule with a proper substrate
induced fit theory
factors affecting enzyme reactions
pH, temperature, and substrate concentration
enzyme’s certain temperature
optimal temperature
how does pH affect enzymes
change in pH slows enzyme activity
