Endergonic thiab exergonic cov tshuaj tiv thaiv
Exergonic cov tshuaj tiv thaiv kuj hu ua spontaneous cov tshuaj tiv thaiv , vim lawv tuaj yeem tshwm sim yam tsis muaj qhov sib ntxiv ntawm lub zog. Cov tshuaj tiv thaiv nrog rau qhov zoo ∆G (∆G> 0), ntawm qhov tod tes, xav tau lub zog nkag thiab hu ua endergonic cov tshuaj tiv thaiv
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov piv txwv ntawm endergonic thiab exergonic cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv endergonic tsis spontaneous. Piv txwv ntawm cov tshuaj tiv thaiv endergonic suav nrog endothermic cov tshuaj tiv thaiv , xws li photosynthesis thiab melting ntawm dej khov rau hauv dej. Yog hais tias qhov kub ntawm ib puag ncig txo qis, lub tshuaj tiv thaiv yog endothermic.
Ib yam li ntawd, qhov piv txwv ntawm kev tawm dag zog yog dab tsi? Ib exergonic cov tshuaj tiv thaiv hais txog a tshuaj tiv thaiv qhov twg lub zog tawm. Cov piv txwv ntawm exergonic cov tshuaj tiv thaiv tshwm sim hauv peb lub cev yog cellular respiration: C6H12O6 (glucose) + 6 O2 -> 6 CO2 + 6 H2O no tshuaj tiv thaiv tso tawm lub zog uas yog siv rau kev ua haujlwm ntawm tes.
Tsuas yog li ntawd, exergonic thiab endergonic txhais li cas?
Exergonic thiab endergonic Cov tshuaj tiv thaiv ua rau muaj kev hloov pauv hauv Gibbs dawb zog. Hauv kev ua haujlwm tshuaj tiv thaiv lub zog dawb ntawm cov khoom yog qis dua ntawm cov reactants; lub caij no hauv endergonic lub zog dawb ntawm cov khoom yog siab tshaj ntawm cov reactants.
Dab tsi yog exergonic cov tshuaj tiv thaiv hauv biology?
Ib exergonic cov tshuaj tiv thaiv (xws li cellular respiration) yog a tshuaj tiv thaiv uas poob zog thaum tus txheej txheem ntawm lub tshuaj tiv thaiv . Ua kom muaj zog (1) catalyzes tshuaj tiv thaiv tshwm sim nyob rau hauv ib tug spontaneous yam.

Dab tsi yog qhov exergonic thiab endergonic cov tshuaj tiv thaiv?
Thaum ib qho tshuaj tiv thaiv ua rau lub zog yog coj los yog tso tawm. Nyob rau hauv ib qho exergonic cov tshuaj tiv thaiv, lub zog raug tso tawm rau ib puag ncig. Cov ntawv cog lus raug tsim muaj zog dua li cov ntawv cog lus tau tawg. Nyob rau hauv ib qho endergonicreaction, lub zog yog absorbed los ntawm cov puag ncig
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv exergonic thiab endergonic cov lus nug?
Exergonic cov tshuaj tiv thaiv muaj ionic bonds; endergonic cov tshuaj tiv thaiv muaj xws li covalent bonds. Nyob rau hauv exergonic cov tshuaj tiv thaiv, cov reactants muaj tshuaj zog tsawg dua cov khoom; nyob rau hauv endergonic cov tshuaj tiv thaiv, qhov opposite yog muaj tseeb. Exergonic kev cuam tshuam cuam tshuam nrog kev rhuav tshem cov ntawv cog lus; endergonic cov tshuaj tiv thaiv cuam tshuam nrog kev tsim cov ntawv cog lus
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
