Qhia vim li cas pyruvate yog qhov tseem ceeb hauv kev sib txuas ntawm cov metabolism. Glycolysis yog ib txwm rau fermentation thiab ua pa ntawm tes. Cov khoom kawg ntawm glycolysis, pyruvate, sawv cev rau lub diav rawg hauv catabolic txoj hauv kev ntawm cov piam thaj oxidation. … Yog hais tias lub cell ua hauj lwm nyuaj thiab nws cov ATP concentration pib poob, ua pa nrawm.
YPyruvate tseem ceeb yog dab tsi?
Pyruvate yog ib qho tshuaj tseem ceeb hauv biochemistry. Nws yog qhov tso tawm ntawm cov metabolism hauv qabzib hu ua glycolysis. Ib qho molecule ntawm qabzib tawg mus rau hauv ob lub molecules ntawm pyruvate, uas yog siv los muab lub zog ntxiv, nyob rau hauv ib qho ntawm ob txoj kev.
Lub hom phiaj tseem ceeb ntawm kev hloov pauv pyruvate yog dab tsi?
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 pyruvate tseem ceeb hauv kev ua pa ntawm tes?
Nqe Lus Nug: Lub luag haujlwm ntawm pyruvate hauv kev ua pa ntawm tes yog dab tsi? Teb: Pyruvates feem ntau muab lub zog rau lub hlwb los ntawm lub voj voog citric acid ua kom lub cev ua pa.
Lub hom phiaj ntawm pyruvate oxidation hauv cellular metabolism yog dab tsi?
Nyob rau hauv prokaryotes, nws tshwm sim hauv cytoplasm. Zuag qhia tag nrho, pyruvate oxidation hloov pyruvate-ib peb-carbon molecule-rau hauv acetyl CoAstart ntawv, C, o, A, kawg ntawv-ib ob-carbon molecule txuas nrog Coenzyme A-ua cov ntawv NADHstart, N, A, D, H, cov ntawv kawg thiab tso tawm ib qho carbon dioxide molecule hauv cov txheej txheem.
