Nyob hauv cov hlwb eukaryotic, cov pyruvate molecules uas tsim thaum kawg ntawm glycolysis raug thauj mus rau mitochondria, uas yog qhov chaw ntawm cellular respiration. Nyob ntawd, pyruvate yuav hloov mus rau hauv ib pawg acetyl uas yuav tau khaws thiab qhib los ntawm cov cab kuj hu ua coenzyme A (CoA).
Qhov twg hauv mitochondria yog pyruvate hloov mus rau acetyl CoA?
Citric Acid Cycle (Krebs Cycle)
Zoo li kev hloov pauv ntawm pyruvate rau acetyl CoA, lub voj voog citric acid tshwm sim hauv lub matrix ntawm mitochondria.
YPuas pyruvate oxidized lossis txo rau acetyl CoA?
Zuag qhia tag nrho, pyruvate oxidation converts pyruvate-ib peb-carbon molecule-rau hauv acetyl CoAstart ntawv, C, o, A, kawg ntawv-ib ob-carbon molecule txuas nrog Coenzyme A-tsim cov ntawv NADHstart, N, A, D, H, cov ntawv kawg thiab tso tawm ib qho carbon dioxide molecule hauv cov txheej txheem.
Yuav ua li cas yog xav tau nyob rau hauv lub cell los hloov pyruvate rau acetyl CoA?
Hauv kev hloov pauv ntawm pyruvate rau acetyl CoA, txhua pyruvate molecule poob ib qho carbon atom nrog tso tawm carbon dioxide. Thaum lub sij hawm tawg ntawm pyruvate, electrons raug xa mus rau NAD + los tsim NADH, uas yuav siv los ntawm tes los tsim ATP.
Vim li cas mitochondria thiaj li muaj nyob rau hauv cov leeg pob txha?
Vim li cas mitochondria thiaj li muaj nyob rau hauv cov leeg pob txha? Lawv xav tau los muab lub zog raunqaij leeg. Cov ntshav ntws loj tshaj plaws hauv cov leeg pob txha. Lawv yuav tsum tau kho cov ntaub so ntswg uas puas thaum lub sij hawm qoj ib ce.

Yuav ua li cas hloov ntawm ib tug tub mus rau ib tug ntxhais nyob rau hauv gta v?
Tam sim no, tsis muaj txoj hauv kev los hloov koj tus cwj pwm poj niam txiv neej hauv GTA Online. Thaum koj tawm hauv cov ntawv qhia tsim ua cim, txawm tias koj xaiv dab tsi - txiv neej lossis poj niam - raug kaw. Kuv yuav hloov kuv poj niam txiv neej li cas hauv GTA Online 2021?
Thaum twg pyruvate ua acetyl coa?
Pyruvate hloov mus rau hauv Acetyl CoA hauv tus txheej txheem nruab nrab ua ntej Citric Acid Cycle. Ntawm no nws hnov mob nrog Coenzyme A. Ntawm no nws poob ob ntawm nws cov pa oxygen thiab ib qho ntawm nws yog carbons los ua carbon dioxide.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Nyob rau hauv cov txheej txheem ntawm glycolysis qabzib hloov mus rau?
Nyob hauv cov hlwb feem ntau glycolysis hloov cov piam thaj rau pyruvateuas yog tom qab oxidized rau carbon dioxide thiab dej los ntawm mitochondrial enzymes. Obligate ATP ntau lawm ntawm glycolysis kuj tshwm sim thaum tsis muaj oxygen txawm tias mitochondria muaj los tsis muaj.
Nyob hauv lub tshuab hluav taws xob kinetic zog hloov mus rau hauv?
Lub tshuab hluav taws xob, tig, hloov lub zog (kinetic) lub zog ntawm lub rotor mus rau hluav taws xob. Lub zog kinetic hloov pauv mus ua dab tsi? Kinetic zog kuj tuaj yeem hloov ntawm ib lub cev mus rau lwm qhov hauv kev sib tsoo, uas tuaj yeem ua elastic lossis inelastic.
