Exergonic cov tshuaj tiv thaiv tso dag zog; endergonicreactions nqus nws. Exergonic cov tshuaj tiv thaiv koom nrog ionicbonds; endergonic cov tshuaj tiv thaiv koom nrog covalent bonds. Hauv exergonic cov tshuaj tiv thaiv , cov reactants muaj tshuaj zog tsawg dua cov khoom; hauv endergonic cov tshuaj tiv thaiv , qhov opposite istrue.
Yog li, 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.
Tsis tas li ntawd, lub zog tseem ceeb txuas ntawm exergonic thiab endergonic cov tshuaj tiv thaiv yog dab tsi? Dab tsi yog qhov kev sib raug zoo ntawm exergonicreactions , endergonic cov tshuaj tiv thaiv thiab siv andregeneration ntawm ATP? Thaum twg zog los ntawm ATP raug tso tawm, nws yog exergonic cov tshuaj tiv thaiv . Thaum ADP thiab inorganic phosphaterelease ces nws yog ib endergonic cov tshuaj tiv thaiv vim nws muaj tobe opposite.
Kuj paub, hom tshuaj tiv thaiv twg yog Endergonic?
Hauv chemical thermodynamics, ib endergonicreaction (tseem hu ua lub tshav kub absorbs nonspontaneous tshuaj tiv thaiv los yog qhov tsis zoo tshuaj tiv thaiv ) yog chemical tshuaj tiv thaiv nyob rau hauv uas tus qauv hloov nyob rau hauv dawb zog ispositive, thiab lub zog yog absorbed.
Puas yog ATP tsim Exergonic lossis Endergonic?
-Yog, endergonic Cov tshuaj tiv thaiv yog ua ke rau hydrolysis ntawm ATP , yog kev ua haujlwm . - Yog, thesynthesis ntawm ATP yog endergonic . ATP tsuas tuaj yeem ua tau yog tias nws yog txuas mus rau ib qho kev ua haujlwm txoj kev xav.

Dab tsi yog qhov txawv ntawm cov lus teb nuclear thiab cov lus teb cytoplasmic? Cov lus teb nuclear cuam tshuam nrog kev hloov pauv ntawm cov noob qhia, thaum cov lus teb cytoplasmic cuam tshuam nrog kev ua kom muaj enzyme lossis qhib ntawm ion channel
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Vim li cas ecologists nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj ntau?
Vim li cas Ecologist nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj qhov sib txawv ntawm ib tus neeg mus rau Biosphere? Txhawm rau nkag siab txog kev sib raug zoo hauv biosphere, ecologists nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj qhov nyuaj ntawm ib tus neeg mus rau tag nrho biosphere
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
