Qhov sib txawv tseem ceeb ntawm fermentation thiab ua pa yog qhov fermentation tshwm sim thaum tsis muaj oxygen thaum ua pa xav tau oxygen.
Cov kab mob xav tau lub zog los ua haujlwm ntawm tes. Yog li, lawv tsim lub zog molecules hauv daim ntawv ntawm ATP. Lawv siv cov substrates sib txawv thiab tawg mus rau hauv ntau hom, thiab lub zog tso tawm hloov mus rau hauv lub zog molecules uas tuaj yeem siv los ntawm cov hlwb. Glucose yog thawj substrate ntawm ntau yam kab mob. Fermentation thiab ua pa yog ob txheej txheej cellular uas tsim lub zog los ntawm kev rhuav tshem cov piam thaj ntawm ob peb kauj ruam. Txawm li cas los xij, kev ua pa ua pa zoo dua thiab tsim cov ATP ntau dua li cov fermentation.
Fermentation yog dab tsi?
Cov kab mob ua rau fermentation los ua ke ATP thaum tsis muaj oxygen. Hauv luv luv, fermentation yog cov txheej txheem ntawm lub zog tsim tawm uas tshwm sim ntawm cov xwm txheej anaerobic. Raws li qhov tshwm sim ntawm fermentation, suab thaj metabolize feem ntau rau effervescent fatty acids. Txij li nws tsis tas yuav muaj cov pa oxygen, nws siv cov piam thaj los ua cov tshuaj reactant thiab tom qab ntawd tsim ATP thiab lwm yam khoom.
Daim duab 01: Fermentation
Thaum thawj fermentation, suab thaj ntawm m altose thiab qabzib hloov mus rau hauv ethanol, lactic acid thiab carbon dioxide. Nws tsim lub zog tsawg (2 ATP) vim nws tsim lub zog ncaj qha los ntawm cov piam thaj. Tsis tas li ntawd, nyob rau hauv fermentation, ib feem puas ntawm cov substrate tshwm sim. Fermentation tuaj yeem tshwm sim ntawm ob txoj hauv kev uas yog ethanol fermentation thiab lactic acid fermentation. Qhov kawg electron txais ntawm fermentation yog cov organic molecule es tsis txhob oxygen. Fermentation feem ntau tuaj yeem pom hauv microbes xws li cov poov xab, kab mob, thiab lwm yam.
Ua pa yog dab tsi?
Ua pa yog txheej txheem cellular ntawm lub zog tsim tawm hauv cov kab mob aerobic. Nws siv cov piam thaj los ua lub substrate thiab los ntawm ib qho kua nplaum molecules, nws synthesizes tag nrho ntawm 36 ATP molecules. Kev ua pa yuav tsum tau oxygen los tsim lub zog. Nws tshwm sim ntawm peb theem loj; glycolysis, Krebs cycle thiab electron thauj saw.
Daim duab 02: Ua pa
Glycolysis tshwm sim hauv cytoplasm ntawm tes thaum Krebs lub voj voog thiab cov saw hluav taws xob thauj khoom tshwm sim hauv mitochondria. Thaum kawg ntawm tag nrho cov txheej txheem, nws yields tus naj npawb ntawm ATP los yog lub zog ntau dua li lwm cov txheej txheem tsim hluav taws xob. Lub zog tsim tawm yog siv rau lwm yam kev ua haujlwm physiological xws li cov leeg mob thiab hluav taws xob impulses.
Dab tsi yog qhov zoo sib xws ntawm Fermentation thiab Respiration?
- Lawv yog cov txheej txheem ntawm tes.
- Ob txheej txheem yog cov txheej txheem catabolic.
- Fermentation thiab Respiration koom nrog hauv kev rhuav tshem cov piam thaj rau hauv lub zog molecules ATP.
Qhov txawv ntawm fermentation thiab ua pa yog dab tsi?
Fermentation thiab ua pa yog ob txheej txheem uas tsim lub zog los ntawm cov piam thaj molecule. Fermentation tsim lub zog yam tsis xav tau cov pa oxygen, uas ua rau kev loj hlob ntawm cov kab mob. Ntawm qhov tod tes, ua pa yuav tsum tau oxygen txhawm rau tsim lub zog los ntawm cov piam thaj, qhov no, tig mus, ua rau cov piam thaj mus dhau glycolysis los tsim pyruvate. Yog li ntawd, qhov sib txawv tseem ceeb ntawm fermentation thiab ua pa yog hais txog cov pa oxygen uas tau hais los saum toj no. Tsis tas li ntawd, cov pyruvate no dhau los hloov pauv cellular qhov twg nws dhau los ntawm cov txheej txheem sib txawv thiab tom qab ntawd tsim ATP ua qhov kawg.
Cov hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm fermentation thiab ua pa hauv daim ntawv teev npe.
Summary – Fermentation vs Respiration
Fermentation tshwm sim thaum lub sijhawm anaerobic. Yog li ntawd, cov piam thaj metabolizes feem ntau rau effervescent fatty acids. Kev ua pa yog txheej txheem uas tsim lub zog los ntawm cov piam thaj thaum muaj cov pa oxygen. Tom qab ntawd lub fermentation, ua pa ua pa ntau ATP los ntawm ib tug qabzib molecule. Tsis tas li ntawd, ib qho kev tawg tag ntawm cov substrate tshwm sim hauv kev ua pa thaum ib nrab tawg tshwm sim hauv fermentation. Qhov no yog qhov txawv ntawm fermentation thiab ua pa.
