Qhov sib txawv tseem ceeb ntawm kev ua pa anaerobic hauv cov nroj tsuag thiab tsiaj txhu yog cov khoom kawg hauv kev ua pa anaerobic ntawm cov nroj tsuag yog ethanol thiab carbon dioxide, thaum cov khoom kawg ntawm cov tsiaj ua pa anaerobic yog lactic acid.
Cellular respiration yog cov txheej txheem metabolic uas tshwm sim hauv cov hlwb ntawm cov kab mob muaj sia. Nws yog cov txheej txheem biochemical uas hloov cov tshuaj zog los ntawm cov as-ham lossis oxygen molecules rau hauv adenosine triphosphate (ATP). Cov txheej txheem no tso cov khoom pov tseg thiab. Cov khoom noj uas muaj ntau tshaj plaws uas siv los ntawm cov nroj tsuag thiab tsiaj hlwb hauv kev ua pa muaj xws li qab zib (glucose), amino acids, thiab fatty acids. Tsis tas li ntawd, cov hlwb siv cov pa oxygen molecular raws li tus neeg sawv cev oxidizing ib txwm, uas muab cov tshuaj lom neeg feem ntau. Feem ntau muaj ob hom kev ua pa xws li aerobic thiab anaerobic, raws li qhov muaj thiab tsis muaj molecular oxygen. Kev ua pa anaerobic hauv cov nroj tsuag thiab tsiaj txhu yog cov txheej txheem uas ua pa tshwm sim thaum tsis muaj molecular oxygen.
Anaerobic Respiration hauv cov nroj tsuag yog dab tsi?
Anaerobic ua pa yog cov txheej txheem ntawm kev tso lub zog hauv kev tswj hwm enzymatically stepwise raws li qhov tsis muaj molecular oxygen. Nws kuj tseem txhais tau tias yog qhov tsis tiav degradation ntawm cov zaub mov organic yam tsis siv cov pa oxygen ua cov oxidant kom zoo. Kev ua pa anaerobic yog hom kev ua pa tshwj xeeb hauv qee cov kab mob parasites, prokaryotes, thiab ntau lub unicellular eukaryotes. Cov khoom kawg hauv kev ua pa anaerobic ntawm cov nroj tsuag yog ethanol thiab carbon dioxide. Vim yog kev tsim cov ethyl cawv, nws tseem hu ua cawv fermentation. Vim yog qhov tsim cov pa roj carbon dioxide, nws muab lub ntsej muag frothy rau cov xov xwm thaum kawg ntawm cov tshuaj tiv thaiv.
Daim duab 01: Kev ua pa tsis ua pa hauv cov nroj tsuag
Tsis tas li ntawd, ob lub npe enzymes koom nrog hauv cov txheej txheem no. Pyruvate decarboxylase yog thawj cytoplasmic enzyme uas hloov pyruvate rau acetaldehyde los ntawm kev tshem tawm ib qho CO 2molecule. Coenzyme thiamine pyrophosphate (TPP) kuj tseem siv rau hauv cov tshuaj tiv thaiv no. Tom qab ntawd, enzyme cawv dehydrogenase hloov acetaldehyde rau hauv ethyl cawv. Rau lub hom phiaj saum toj no, hydrogen yog tau los ntawm NADH, uas yog tsim thaum lub sij hawm glycolysis. Feem ntau, 2ATP yog tsim los ntawm hom anaerobic ua pa. Ntxiv mus, cov dej cawv ntau dhau ntawm qhov txwv yuav ua rau cov nroj tsuag puas tsuaj.
Dab tsi yog qhov ua pa anaerobic hauv Tsiaj txhu?
Anaerobic respiration nyob rau hauv cov tsiaj tshwm sim nyob rau hauv cov leeg hlwb thaum tsis muaj molecular oxygen. Cov khoom kawg hauv kev ua pa anaerobic ntawm cov tsiaj yog lactic acid. Yog li ntawd, nws tseem hu ua homolactic fermentation. Lactic acid tsim nyob rau hauv cov leeg nqaij ncaj qha xa mus rau lub siab kom rov tsim cov piam thaj. Feem ntau, hauv lactic acid fermentation, pyruvic acid uas tsim nyob rau hauv glycolysis yog ncaj qha txo los ntawm NADH los tsim lactic acid.
Daim duab 02: Kev ua pa tsis ua pa hauv tsiaj txhu
Tsis muaj CO2 roj ntau lawm hauv cov tshuaj tiv thaiv no. Lub enzyme uas catalyzes cov tshuaj tiv thaiv no yog lactic dehydrogenase, uas yuav tsum tau coenzyme FMN (flavin mononucleotide) thiab cofactor Zn 2+ Tsis tas li ntawd, 2ATP yog tsim los ntawm kev ua pa anaerobic hauv cov tsiaj (lactic acid fermentation).
Dab tsi yog qhov zoo sib xws ntawm anaerobic ua pa hauv cov nroj tsuag thiab tsiaj txhu?
- Anaerobic ua pa hauv cov nroj tsuag thiab tsiaj txhu tshwm sim thaum tsis muaj molecular oxygen.
- Nyob rau hauv ob txoj kev, ob ATP raug tsim.
- Ob txheej txheem cuam tshuam nrog kev ua tsis tiav ntawm kev ua pa substrate.
- Nyob rau hauv cov txheej txheem no, NADH tsim nyob rau hauv glycolysis feem ntau yog siv.
- Electron thauj saw tsis tuaj nyob hauv ob txoj kev.
- Lawv yog ob qho tshuaj tiv thaiv enzyme-catalyzed.
Dab tsi yog qhov sib txawv ntawm Kev Ua pa anaerobic hauv cov nroj tsuag thiab tsiaj txhu?
Cov khoom kawg hauv kev ua pa anaerobic ntawm cov nroj tsuag yog ethanol thiab carbon dioxide, thaum cov khoom kawg hauv cov tsiaj ua pa anaerobic yog lactic acid. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev ua pa anaerobic hauv cov nroj tsuag thiab tsiaj txhu. Ntxiv mus, CO2 tso tawm los ntawm cov tshuaj tiv thaiv ua rau foaming nyob rau hauv lub anaerobic ua pa ntawm cov nroj tsuag tab sis tsis nyob rau hauv lub anaerobic ua pa ntawm cov tsiaj.
Cov infographic hauv qab no teev qhov sib txawv ntawm kev ua pa anaerobic hauv cov nroj tsuag thiab tsiaj txhu hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Anaerobic Respiration in Plants vs Tsiaj
Anaerobic ua pa hauv cov nroj tsuag thiab tsiaj txhu yog txheej txheem uas ua pa tshwm sim thaum tsis muaj molecular oxygen. Hauv kev ua pa anaerobic, cov hlwb tsis siv cov pa oxygen molecular ua tus neeg sawv cev oxidizing. Ntxiv mus, anaerobic ua pa ntawm cov nroj tsuag yog txheej txheem uas tsim ethanol thiab carbon dioxide ua cov khoom kawg. Ntawm qhov tod tes, anaerobic respiration ntawm cov tsiaj yog ib tug txheej txheem uas tsim lactic acid raws li ib tug kawg khoom. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev ua pa anaerobic hauv cov nroj tsuag thiab tsiaj.
