Tsis muaj oxygen , pyruvate ua ( pyruvic acid ) tsis yog metabolized los ntawm cellular respiration tab sis undergoes tus txheej txheem ntawm fermentation. Cov pyruvate ua tsis yog thauj mus rau hauv mitochondrion, tab sis tseem nyob hauv cytoplasm, qhov twg nws hloov mus rau cov khoom pov tseg uas yuav raug tshem tawm ntawm lub cell.
Yog li ntawd, pyruvate oxidation tshwm sim qhov twg?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis hauv cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate ua yuav tsum nkag mus rau mitochondrion, hla nws cov ntaub so ntswg thiab tuaj txog ntawm matrix.
Tsis tas li, yuav ua li cas yog tias pyruvate oxidation raug thaiv? Yog tias pyruvate oxidation raug thaiv , dab tsi yuav tshwm sim mus rau theem ntawm oxaloacetate thiab citric acid nyob rau hauv lub voj voog citric acid qhia hauv daim duab hauv qab no? Oxaloacetate yuav sib sau thiab citric acid yuav txo qis. Ob qho tib si oxaloacetate thiab citric acid yuav khaws cia. Ob qho tib si oxaloacetate thiab citric acid yuav txo qis.
Ib sab ntawm qhov no, yuav ua li cas rau pyruvate thaum muaj oxygen?
Txawm tias glycolysis tsis xav tau oxygen , txoj hmoo ntawm pyruvate ua molecules nyob ntawm seb muaj oxygen . Yog oxygen tsis muaj, cov pyruvate ua hloov mus rau lactate, thiab tsis muaj ATP ntxiv yog tsim los ntawm qhov kev hloov pauv no. Yog muaj oxygen , cov pyruvates raug thauj mus rau hauv mitochondrial matrix.
Puas yog kev hloov pauv ntawm pyruvate rau acetyl CoA xav tau oxygen?
Kev ua pa aerobic tshwm sim hauv mitochondria thiab xav tau lub xub ntiag ntawm oxygen . Aerobic respiration pib nrog lub Kev hloov pauv ntawm pyruvate rau hauv acetyl CoA.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Qhov twg hauv mitochondria puas pyruvate oxidation tshwm sim?
Pyruvate yog tsim los ntawm glycolysis hauv cytoplasm, tab sis pyruvate oxidation tshwm sim hauv mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
Yuav ua li cas oxygen tshwm sim hauv xwm piav qhia txog lub voj voog oxygen hauv qhov xwm txheej?
Piav lub voj voog oxygen hauv qhov xwm txheej. Oxygen muaj nyob rau hauv ob hom sib txawv hauv qhov xwm txheej. Cov ntaub ntawv no tshwm sim raws li cov pa roj carbon monoxide 21% thiab ua ke hauv daim ntawv oxides ntawm hlau thiab nonmetals, nyob rau hauv lub ntiaj teb crust, cua thiab dej. Oxygen rov qab mus rau qhov chaw los ntawm cov txheej txheem hu ua photosynthesis
Puas muaj mitosis tshwm sim yam tsis muaj cytokinesis?
Mitosis (ib theem hauv lub voj voog ntawm tes) tshwm sim tom qab DNA hauv ib lub xovtooj tau muab luam tawm, txhais tau tias muaj ob pawg chromosomes hauv ib lub xovtooj. Qhov tshwm sim ntawm mitosis yam tsis muaj cytokinesis yuav yog ib lub xovtooj ntawm ntau tshaj ib lub nucleus. Xws li ib tug cell hu ua multinucleated cell. Qhov no tuaj yeem yog ib qho txheej txheem
