Qhov sib txawv tseem ceeb ntawm endergonic thiab exergonic yog qhov kev tawm tsam endergonic tsis yog tus kheej thiab tsis zoo, qhov kev tawm tsam exergonic yog tus kheej thiab nyiam.
Lub zog yog lub peev xwm ua haujlwm. Nyob rau hauv ib lub cev, lub zog tuaj yeem ua haujlwm thiab lub zog tuaj yeem hloov mus rau lwm yam xws li cua sov, suab, lub teeb thiab lwm yam. Thaum lub zog ntawm lub cev hloov pauv vim qhov kub ntawm qhov sib txawv ntawm qhov system thiab ib puag ncig, peb hais tias lub zog. tau pauv raws li cua sov. Ib qho tshuaj tiv thaiv tuaj yeem suav hais tias yog qhov system. Cov tshuaj tiv thaiv tshuaj yog ib txoj hauv kev uas ib los yog ntau lub tebchaw hloov mus rau hauv ib txheej tshiab ntawm cov tebchaw los ntawm kev hloov pauv ntau.
Thaum cov tshuaj tiv thaiv tshwm sim, tuaj yeem hloov pauv lub zog los ntawm ib puag ncig mus rau qhov system lossis rov ua dua. Qee qhov kev tshwm sim no tshwm sim, thiab qee qhov tsis yog. Tag nrho cov kev tshwm sim tshwm sim hauv ib puag ncig tsis yog tshwm sim, tab sis peb pom cov kev cuam tshuam uas tsis yog tshwm sim tshwm sim ib txwm muaj. Qhov ntawd yog vim tsis muaj qhov tshwm sim tshwm sim ua ke nrog cov tshuaj tiv thaiv tus kheej thiab lawv tau tsav los ntawm lub zog ntawm cov tshuaj tiv thaiv spontaneous.
Endergonic yog dab tsi?
Lo lus "ender" yog los ntawm lo lus "endo" uas txhais tau tias "hauv". Yog li, endergonic txhais tau tias nqus lub zog hauv daim ntawv ntawm kev ua haujlwm. Yog li ntawd, nyob rau hauv ib qho endergonic cov tshuaj tiv thaiv, cov nyob ib puag ncig muab lub zog rau hauv lub cev. Tsis tas li ntawd, cov khoom yuav muaj zog ntau dua li cov reactants. Ib qho endergonic cov tshuaj tiv thaiv yog suav hais tias yog tsis raws cai lossis tsis zoo. Yog tias qhov kev hloov hluav taws xob no tshwm sim ntawm qhov siab thiab qhov kub thiab txias, tus qauv Gibbs dawb lub zog yuav zoo. Yog li, qhov sib npaug tsis tu ncua rau qhov kev tawm tsam endergonic tsawg dua ib qho.
Photosynthesis yog ib qho endergonic cov tshuaj tiv thaiv uas siv qhov chaw nyob hauv ib puag ncig ntuj. Rau photosynthesis, lub zog yog muab los ntawm hnub ci. Hauv tib neeg lub cev, thaum muaj kev cuam tshuam endergonic tshwm sim, lub zog tau muab los ntawm ATP. Li no, endergonic cov tshuaj tiv thaiv yog ua ke nrog ATP hydrolysis cov tshuaj tiv thaiv.
Exergonic yog dab tsi?
Exergonic txhais tau tias tso lub zog hauv kev ua haujlwm. Nyob rau hauv cov kev tshwm sim no, lub zog tawm ntawm lub cev mus rau sab nraud. Exergonic cov tshuaj tiv thaiv yog qhov zoo thiab muaj txiaj ntsig.
Vim tias lub zog tawm thaum lub sijhawm cov tshuaj tiv thaiv, cov khoom muaj zog tsawg dua li cov reactants. Yog li, qhov hloov pauv enthalpy (∆H) ua qhov tsis zoo. Ntxiv mus, yog tias kev hloov pauv tau ua tiav ntawm qhov siab thiab qhov kub thiab txias, tus qauv Gibbs dawb lub zog yuav yog tus nqi tsis zoo.
Qhov txawv ntawm Endergonic thiab Exergonic yog dab tsi?
Endergonic txhais tau tias nqus lub zog hauv daim ntawv ua haujlwm thaum exergonic txhais tau tias tso lub zog hauv daim ntawv ua haujlwm. Qhov sib txawv tseem ceeb ntawm endergonic thiab exergonic yog tias cov tshuaj tiv thaiv endergonic tsis yog tus kheej thiab tsis zoo, qhov kev tawm tsam exergonic yog tus kheej thiab nyiam. Tus qauv Gibbs dawb lub zog yuav ua tau zoo nyob rau hauv endergonic cov tshuaj tiv thaiv, nyob rau hauv sib piv rau exergonic cov tshuaj tiv thaiv. Nyob rau hauv exergonic cov tshuaj tiv thaiv, cov khoom muaj tsawg zog tshaj cov reactants tab sis, nyob rau hauv endergonic cov tshuaj tiv thaiv, cov khoom muaj zog ntau dua li reactants.
Summary – Endergonic vs Exergonic
Endergonic txhais tau tias nqus lub zog hauv daim ntawv ua haujlwm thaum exergonic txhais tau tias tso lub zog hauv daim ntawv ua haujlwm. Qhov sib txawv tseem ceeb ntawm endergonic thiab exergonic yog tias endergonic cov tshuaj tiv thaiv tsis yog tus kheej thiab tsis zoo, qhov kev tawm tsam exergonic yog tus kheej thiab nyiam.
