LAB po7: pocatalyst po- poCORRECT poANSWER po-substance pothat pospeeds poup pothe porate poof poa pochemical
reaction
LAB po7: poEnzmes po- poCORRECT poANSWER po-Proteins powhich poserve poas pocatalysts pofor pocertain pochemical
poreactions
LAB po7: poenergy poof poactivation po- poCORRECT poANSWER po-
The poamount poof poenergy pothat poreactants pomust poabsorb pobefore poa pochemical poreaction powill postart
LAB po7: poActive posite poof poan poenzyme po- poCORRECT
poANSWER po- pothe poregion poof poan poenzyme pothat
poattachesRto poa posubstrate
LAB po7: poHow podo poenzymes pocatalyze poreactions? po- poCORRECT
poANSWER po- poby polowering pothe poactivation poenergy porequired pofor
pothe poreaction poto pooccur
LAB po7: poWhat poare pothe poseven pomajor poproperties poof poenzymes? po- poCORRECT poANSWER po-Most poare
poproteins.
They poare pohighly pospecific; pomost powill poonly poreact powith poa pocertain posubstrate.
They poform poan poenzyme-substrate
complex: poE po+S↔ES po→P po+E
po
They podo ponot poaffect pothe podirection poof poa poreaction.
They polower pothe poenergy poof poactivation poof poa poreaction.
They poare ponot poconsumed poin pothe poreaction.
They poare pooften pohighly poregulated.
, LAB po7: poHow podo poinhibitors powork? po- poCORRECT poANSWER po-
by popreventing poreactants pofrom pocoming potogether pobecause pothey pohave poa posimilar poshape poto pothe
posubstrate pomolec poule.
Therefore poless posubstrate pomolecules pocan pobind poto pothe poenzymes poso pothe poreaction porate pois podecreased.
LAB po7: poHow podo podifferent posubstrates poaffect pothe porate poof poenzyme poreactions? po- poCORRECT poANSWER po-
The popresence poor poabsence poof poa pospecific pochemical pofunctional pogroup pocan podecide pohow powell pothe
poenzyme poworks pofor pothat poreaction.
The poability poof pothe poenzyme poto powork powell powith pocertain posubstrates poand ponot powell powith poother
posimilar posubstrates pois pocalled pospecificity.
LAB po7: poenzyme pospecificity po- poCORRECT poANSWER po-
The poability poof pothe poenzyme poto powork powell powith pocertain posubstrates poand ponot powell powith poother posimilar
posubstrates
LAB po7: poHow podoes posubstrate poconcentration poaffect pothe porate poof poenzyme poreactions? po- poCORRECT
poANSWER po- poEnzymes poare ponot poconsumed poin pothe poreaction, poso posmall poamounts poof poan poenzyme pocan
powork powell poon polarge poamo pounts poof posubstrate.
Increasing poamounts poof posubstrate powill poplateau pothe poactivity poof poa pofixed poamount poof poenzyme, potaking
polonger poto poc poonvert posubstrate pointo poproduct.
Increasing poamounts poof poenzyme powill poincrease pothe porate poof poreaction.
LAB po7: poHow podoes popH poaffect pothe porate poof poenzyme poreactions? po- poCORRECT poANSWER po-
Changes poin popH pocan poaffect pothe pofunctional pogroups poof pocertain poamino poacids, powhich pochange potheir
pocharge poor pointe pormolecular pointeractions.
This pocan poinfluence pothe postructure poof pothe poenzyme.
Extreme popH polevels pocan podenature poenzymes, porendering pothem pononfunctional.
