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.
