Txhais kev fermentation. Lub zog tsim cov tshuaj biochemical uas cov organic molecules ua haujlwm rau ob qho tib si as ib electron acceptor thiab pub tshwm sim nyob rau hauv cov xwm txheej anaerobic.
Yog li ntawd, dab tsi yog electron pub rau hauv kev ua pa?
aerobic ua pa , siv hydrogen li electron pub Gene Ontology Term (GO: 0019412) Txhais: oxidation ntawm hydrogen (H2) rau dej (H2O), siv oxygen (O2) ua electron txais . Ib qho hydrogenase enzyme khi H2 thiab hydrogen atoms dhau los ntawm ib qho hluav taws xob Hloov cov saw hlau rau O2 los ua dej.
Tom qab ntawd, lo lus nug yog, vim li cas txoj kev loj hlob ntawm cov xim liab yog qhov tsis zoo thaum cov zinc ntxiv? Txij li thaum zinc txo nitrates rau nitrites, liab los yog xim liab yuav tshwm sim thiab txheeb xyuas qhov tseeb tias nitrates tsis raug txo kom nitrites los ntawm cov kab mob (a kev kuaj tsis zoo ). Kom paub meej, koj ntxiv ib pinch zinc hmoov.
Ua raws li qhov no, cov molecules twg tuaj yeem ua tus txais hluav taws xob thaum ua pa?
Hauv cov kab mob aerobic ua pa, electrons raug xa mus rau ib qho electron thauj saw , thiab qhov kawg electron acceptor yog Oxygen . Molecular Oxygen yog tus neeg sawv cev oxidizing heev thiab, yog li ntawd, yog ib qho zoo heev electron txais.
Kev sib raug zoo ntawm bioluminescence thiab quorum sensing yog dab tsi?
Kev tswj ntawm bio-luminescence Yog li, kab mob bioluminescence yog tswj los ntawm kev sib txuas lus tshuaj hu ua pawg ntseeg . Qhov tseem ceeb, qee qhov taw qhia cov cim npe hu ua autoinducers nrog cov kab mob tshwj xeeb tau ua haujlwm thaum cov pej xeem cov kab mob siab txaus.

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
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
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 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
