Ib exergonic cov tshuaj tiv thaiv hais txog a tshuaj tiv thaiv qhov twg lub zog tawm. Cov piv txwv ntawm kev ua txhaum cai tshwm sim nyob rau 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.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ib qho piv txwv ntawm cov tshuaj tiv thaiv endergonic?

Piv txwv ntawm endergonic cov tshuaj tiv thaiv suav nrog kev kub siab cov tshuaj tiv thaiv , xws li photosynthesis thiab thev naus laus zis ntawm cov dej khov rau hauv cov dej ua kua.

Tsis tas li ntawd, dab tsi yog qhov exergonic thiab endergonic cov tshuaj tiv thaiv? Hauv ib endergonic cov tshuaj tiv thaiv , lub zog yog absorbed los ntawm ib puag ncig. Cov no piav qhia exergonic thiab endergonicreactions Thaum lub zog tso tawm los yog absorbed yog tshav kub zog. In ib qho exothermic tshuaj tiv thaiv qhov kub ntawm cov puag ncig nce. Hauv ib qho endothermic tshuaj tiv thaiv qhov kub ntawm qhov chaw ib puag ncig txo qis.

Xav txog qhov no, dab tsi yog exergonic cov tshuaj tiv thaiv hauv biology?

Ib exergonic cov tshuaj tiv thaiv (xws li cellularrespiration) yog a tshuaj tiv thaiv uas poob zog thaum cov 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 txawv ntawm exergonic thiab exothermic?

Hauv kev xaus, whereas, ib kev ua haujlwm cov tshuaj tiv thaiv txhais tau hais tias cov tshuaj tiv thaiv yog tus kheej, ib exothermic cov tshuaj tiv thaiv tsis muaj dab tsi ua nrog spontaneity, tab sis hais tias lub zog tawm mus rau ib puag ncig. Rau ib exothermic cov tshuaj tiv thaiv, ΔH<0.
