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
amount of energy required for an enzyme to proceed
activation energy
peak of required activation energy
transition state
