Glycolysis, uas yog thawj kauj ruam hauv txhua hom cellular ua pa yog anaerobic thiab tsis xav tau oxygen . Yog oxygen tam sim no, txoj hauv kev yuav txuas ntxiv mus rau lub voj voog Krebs thiab oxidative phosphorylation. Txawm li cas los xij, yog tias oxygen tsis yog tam sim no, qee cov kab mob tuaj yeem ua rau fermentation mus txuas ntxiv tsim ATP.
Hais txog qhov no, cov pa oxygen cuam tshuam li cas rau kev ua pa ntawm tes?
Ntxiv cov tshuaj tiv thaiv ntau ntxiv, zoo li cov piam thaj, ua kom nrawm dua thaum cov enzyme nce mus txog qhov nrawm tshaj plaws. Siab cov pa oxygen tso cai rau cell ua aerobic respiration , uas yuav tsum tau oxygen ua ATP thiab tsim ntau ATP ntau dua li qhov tsis muaj oxygen , hu ua anaerobic ua pa.
Yuav ua li cas rau pyruvate thaum tsis muaj oxygen? Thaum twg oxygen tsis nyob, pyruvate yuav ua cov txheej txheem hu ua fermentation. Nyob rau hauv tus txheej txheem ntawm fermentation NADH + H + los ntawm glycolysis yuav rov qab siv dua rau NAD+ yog li ntawd glycolysis tuaj yeem ua tau txuas ntxiv. Fermentation ua tsis xav tau oxygen thiab yog li ntawd anaerobic.
Ib qho yooj yim, lub npe ntawm kev ua pa uas tshwm sim thaum tsis muaj oxygen yog dab tsi?
Anaerobic Ua pa
Puas tsis muaj oxygen cuam tshuam txog kev ua pa ntawm tes?
Cov piam thaj tau tawg sib nrug, tsim lub zog, khaws cia hauv daim ntawv ntawm ATP, thiab cov pa roj carbon dioxide thiab dej ua cov khoom pov tseg. Yog tias oxygen cov khoom lag luam tsis txaus, lossis tsis muaj, lub xov tooj ntawm tes hloov pauv mus rau qhov tsis muaj zog fermentation los tsim lub zog. Txoj kev no nrawm dua, tab sis tsis zoo li aerobic ua pa.

Qhov twg ntawm cov hauv qab no yog qhov muaj peev xwm tshwm sim tshwm sim ntawm kev tswj hwm procainamide?
Muaj ntau cov kev mob tshwm sim tom qab induction ntawm procainamide. Cov kev tsis zoo no yog ventricular dysrhythmia, bradycardia, hypotension thiab poob siab. Cov kev phom sij tshwm sim ntau dua yog tias cov koob tshuaj txhua hnub tau nce. Procainamide kuj tseem tuaj yeem ua rau kub cev tshuaj thiab lwm yam kev ua xua
Dab tsi yog qhov teeb meem ntawm daim tawv nqaij uas tshwm sim los ntawm kev mob ntev ntawm cov qog sebaceous tshwm sim los ntawm cov khoom zais cia?
AKA pob txuv vulgaris- Cov teeb meem ntawm daim tawv nqaij ua rau mob ntev ntawm cov qog sebaceous los ntawm khaws cia tso zis thiab Propionbacterium acnes, lub sijhawm tshawb fawb rau cov kab mob pob txuv. Qhov mob ntawm daim tawv nqaij qhuav, tawv nqaij vim tsis muaj lossis tsis muaj sebum uas tshwm sim los ntawm cov laus thiab los ntawm qhov txias
Dab tsi yog qhov tshwm sim ntawm lub cev uas tshwm sim los ntawm kev ntxhov siab?

Yuav muaj dab tsi tshwm sim thaum lub plawv nqaij tsis muaj oxygen?
Myocardial infarction (MI), feem ntau paub tias yog lub plawv nres, tshwm sim thaum ib feem ntawm lub plawv tsis muaj oxygen vim qhov txhaws ntawm cov hlab plawv. Cov hlab ntsha hlab ntshav muab cov leeg nqaij hauv plawv (myocardium) nrog cov ntshav oxygenated. Yog tsis muaj oxygen, cov leeg hlwb tau txais kev pab los ntawm cov hlab ntsha uas thaiv cov hlab ntsha pib tuag (infarct)
