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 yuav tsum nkag mus rau hauv mitochondrion , hla nws daim nyias nyias thiab tuaj txog ntawm matrix.
Xav txog qhov no, dab tsi yog cov reactants ntawm pyruvate oxidation?
2 NADH , 2 CO2, 2 Acetyl Co A.
Tsis tas li ntawd, pyruvate nkag mus rau mitochondria li cas? Kev thauj mus los ntawm pyruvate ua rau hauv mitochondria yog los ntawm kev thauj cov protein pyruvate ua translocase. Pyruvate translocase thauj pyruvate ua nyob rau hauv ib tug symport zam nrog ib tug proton, thiab li no yog active, siv zog. Thaum nkag mus rau lub mitochondria , cov pyruvate ua yog decarboxylated, tsim acetyl-CoA.
Qhov thib ob, qhov twg glycolysis tshwm sim hauv lub cell?
Glycolysis siv qhov chaw hauv cytoplasm. Nyob rau hauv lub mitochondrion, lub citric acid voj voog tshwm sim nyob rau hauv lub mitochondrial matrix, thiab oxidative metabolism tshwm sim nyob rau hauv lub puab folded mitochondrial membranes (cristae).
Lub luag haujlwm tseem ceeb ntawm pyruvate yog dab tsi?
Pyruvate yog ib tseem ceeb chemical compound hauv biochemistry. Nws yog qhov tsim tawm ntawm cov metabolism hauv qabzib hu ua glycolysis. Ib qho molecule ntawm qabzib tawg mus rau hauv ob molecules ntawm pyruvate ua , uas yog siv los muab lub zog ntxiv, hauv ib qho ntawm ob txoj kev.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Dab tsi organelle yog sib sau ua ke nyob rau hauv lub nucleolus ntawm lub nucleus?
Lub nucleolus yog lub subdomain nuclear uas sib sau ua ke ribosomal subunits hauv eukaryotic hlwb. Lub nucleolar organizer cheeb tsam ntawm chromosomes, uas muaj cov noob rau pre-ribosomal ribonucleic acid (rRNA), ua lub hauv paus rau nucleolar qauv
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Qhov twg photosynthesis tshwm sim nyob rau hauv ib lub xeev nplooj uas organelles nqa tawm photosynthesis?
Tshuaj chloroplast
Dab tsi organelle yog lub luag haujlwm rau kev thauj khoom hauv thiab tawm ntawm lub cell?
Function Of Cell Organelles A B cell membrane tswj kev txav mus rau hauv thiab tawm ntawm lub cell cytoplasm watery khoom uas muaj ntau cov ntaub ntawv koom nrog hauv cell metabolism endoplasmic reticulum ua txoj hauv kev rau kev thauj khoom thoob plaws hauv lub cell
