Lub cev nyob rau hauv cov xwm txheej zoo li no tsis tuaj yeem noj cov pa oxygen txaus. Pyruvate yog tsim los ntawm glycolysis, nkag mus rau hauv Krebs voj voog thiab tsim lub zog molecules. Nws yog lub hauv paus ntawm ATP molecules. Pyruvate, thaum tsis muaj oxygen, hloov nws txoj hauv kev thiab tsim cov lactic acid molecule.
Pyruvic acid hloov mus rau lactic acid nyob qhov twg?
Yog li Pyruvic acid hloov mus ua lactic acid hauv cytoplasm ntawm cov leeg hlwb thaum lub sijhawm tsis muaj oxygen hauv tib neeg.
Yuav ua li cas thiaj tsis muaj oxygen?
vim tsis muaj oxygen anaerobic ua pa tshwm sim thiab muaj kev tsim ntawm lactic acid hauv tib neeg cov leeg nqaij thiab cawv yog tsim nyob rau hauv cov poov xab.
Thaum twg tsis muaj oxygen hauv cov leeg cov pyruvate hloov mus ua?
Thaum tsis muaj oxygen, pyruvate hloov mus rau lactic acid (lactate), uas ua rau cov leeg qaug zog. Cov txheej txheem no hu ua lactic acid fermentation.
Yuav ua li cas rau Pyruvic acid thaum tsis muaj oxygen hauv tib neeg?
Nyob rau hauv cov xwm txheej anaerobic, qhov tsis muaj oxygen, pyruvic acid tuaj yeem dhau los ntawm cov kab mob mus rau hauv ib qho ntawm peb txoj hauv kev: lactic acid fermentation, cawv fermentation, lossis cellular (anaerobic) ua pa. … Tib neeg ferment lactic acid nyob rau hauv cov nqaij ntshiv uas oxygen yuav depleted, ua rau hauv zos anaerobic tej yam kev mob.
