Fermentation vs Anaerobic Respiration
Anaerobic ua pa thiab fermentation yog ob txoj kev sib txawv nrog cov cim sib txawv ntawm ob. Txawm li cas los xij, ob qhov txheej txheem yog qhov sib txawv hauv qee qhov xwm txheej. Yog li ntawd, nws yog ib qho tseem ceeb heev kom nkag siab txog cov yam ntxwv ntawm ob txheej txheem txhawm rau txheeb xyuas qhov twg yog qhov twg. Kab lus no qhia txog cov yam ntxwv ntawm ob txheej txheem thiab ua qhov kev sib piv ncaj ncees thaum kawg.
Fermentation yog txheej txheem uas lub zog tau muab rho tawm los ntawm cov organic tebchaw uas siv cov khoom siv hluav taws xob endogenous. Lub endogenous electron acceptor feem ntau yog cov organic compound, whereas oxygen ua raws li cov electron txais nyob rau hauv aerobic respiration. Lub zog kuj tau muab rho tawm los ntawm cov organic tebchaw xws li carbohydrates, proteins, rog, thiab lwm yam khoom noj. Fermentation yog ntau txoj kev lag luam muaj txiaj ntsig zoo, vim nws tau siv ntau yam kev lag luam ntawm kev tsim khoom xws li cawv, cawv, npias, thiab tshuaj yej. Kev siv cov kab mob fermenting yog qhov tseem ceeb hauv cov txheej txheem kev lag luam. Lactic acid fermentation thiab cawv fermentation yog qhov paub zoo tshaj plaws ntawm hom no, qhov twg ib qho txheej txheem ua rau lactic acid thaum lwm qhov yields cawv lossis ethanol. Fermentation ntawm acetic acid yields methane thiab carbon dioxide. Tsis tas li ntawd, muaj ntau yam txheej txheem fermentation uas tsim cov roj hydrogen, vim li ntawd. Cov kauj ruam ntawm glycolysis hauv kev ua pa yog txheej txheem ntawm fermentation, qhov twg pyruvate thiab ATP yog tsim los ntawm cov piam thaj. Lactic acid fermentation tshwm sim thaum tsis muaj oxygen los yog tsis tau nkag mus rau hauv cov leeg nqaij, uas ua rau cramps. Yog li ntawd, nws yog qhov nthuav kom pom tias fermentation tshwm sim nyob rau hauv ob qho tib si aerobic thiab anaerobic txoj kev.
Anaerobic Ua pa
Kev ua pa yog ib qho tseem ceeb kom tau txais lub zog, tab sis tsis yog txhua qhov chaw hauv ntiaj teb muaj cov pa oxygen, thiab qhov ntawd xav kom cov kab mob hloov pauv nrog cov txheej txheem sib txawv kom nyob hauv ib puag ncig zoo li no. Kev ua pa anaerobic yog ib txoj hauv kev ntawm kev rho tawm lub zog los ntawm cov ntaub ntawv organic siv lwm cov tshuaj viz. sulphate los yog nitrate compounds raws li qhov kawg electron txais nyob rau hauv cov txheej txheem. Tsis tas li ntawd, cov khoom siv hluav taws xob ntawm lub davhlau ya nyob twg no tsis tshua muaj txiaj ntsig hauv lawv cov peev xwm txo qis thiab tsuas tuaj yeem tsim ob peb ATP molecules rau ib cov piam thaj molecule. Feem ntau, cov khoom pov tseg yog sulfides, nitrites, lossis methane thiab cov ntxhiab tsw tsw zoo rau tib neeg thiab lwm yam tsiaj feem ntau. Lactic acid yog lwm cov pov tseg uas tsim los ntawm kev ua pa anaerobic. Nws yog qhov nthuav kom paub tias kev ua pa anaerobic tuaj yeem tshwm sim hauv tib neeg lub cev ib yam nkaus, tshwj xeeb tshaj yog thaum muaj kev xav tau ntau ntawm oxygen los ua haujlwm cov leeg nqaij sai. Hauv cov xwm txheej zoo li no, lactic acid raug tsim, thiab ua rau cov leeg mob.
Qhov txawv ntawm Fermentation thiab Anaerobic Respiration yog dab tsi?
• Fermentation yog ib txoj kev uas lub zog yog tsim los ntawm cov organic tebchaw siv endogenous electron txais, thiab muaj ntau hom electron txais. Txawm li cas los xij, kev ua pa anaerobic siv ob qho tib si endogenous lossis exogenous non-oxygen compounds raws li cov khoom siv hluav taws xob hauv cov txheej txheem.
• Fermentation muaj nyob rau hauv ob qho tib si aerobic thiab anaerobic ua pa, tab sis tsis anaerobic ua pa.
• Fermentation yog siv los ua kev lag luam tab sis tsis yog kev ua pa anaerobic.
• Caw thiab lactic acid yog cov khoom pov tseg tseem ceeb ntawm fermentation tab sis tsis tas li hauv kev ua pa anaerobic.
