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.
