Thawj Qauv
Hauv nws qhov yooj yim tshaj plaws, hemoglobin cov yog tsim los ntawm cov amino acids sib txuas ua ke hauv cov saw hlau. Cov saw no yog polypeptides uas tseem nyam mus rau hauv heme molecule, uas yog qhov uas cov pa oxygen yuav kawg.
Kuj paub, tus qauv ntawm Hemoglobin yog dab tsi?
Hemoglobin yog cov protein thauj cov pa oxygen ntawm cov qe ntshav liab thiab yog cov protein thoob ntiaj teb nrog rau ib tus neeg laus qauv . Hemoglobin muaj plaub polypeptide subunits; 2 alpha chains thiab ob beta chains. Hemoglobin thauj cov pa oxygen hauv cov ntshav los ntawm lub ntsws mus rau lwm lub cev.
Dab tsi yog cov qauv protein yog Hemoglobin? Hemoglobin yog protein ntau uas ua rau ntshav liab. Nws muaj plaub leeg protein ntau cov saw hlau, ob txoj hlua khi alpha thiab ob txoj hlua beta, txhua tus muaj lub nplhaib zoo li heme pawg uas muaj cov hlau atom. Oxygen khi rov qab rau cov hlau atoms thiab thauj los ntawm cov ntshav.
Thiab lo lus nug yog, dab tsi yog cov qauv thiab ua haujlwm ntawm Hemoglobin?
Hemoglobin tau pom hauv cov qe ntshav liab thiab nqa cov pa oxygen los ntawm lub ntsws mus rau cov nqaij hauv lub cev. Nws kuj tseem pab thauj hydrogen ions thiab carbon dioxide rov mus rau lub ntsws. Hemoglobin muaj peev xwm khi rau oxygen (O2) thiab cov pa roj nitric oxide (NO).
Puas yog hemoglobin muaj tus qauv thib ob?
Ib tus zuj zus, txhua tus alpha helix yog a thib ob polypeptide qauv ua los ntawm cov amino acid chains. Cov amino acids nyob rau hauv lem thawj qauv ntawm hemoglobin cov . Plaub tus qauv thib ob cov saw muaj cov hlau atom nyob hauv qhov hu ua pawg heme, lub nplhaib zoo li lub cev qauv.

Dab tsi yog qhov tseem ceeb lom tseem ceeb ntawm Glycogenesis?
Lub hom phiaj tseem ceeb ntawm glycogenesis yog kom ntseeg tau tias lub cev tsis muaj piam thaj. Glucose yog qhov tseem ceeb vim nws yog lub cev qhov tseem ceeb ntawm lub zog. Yog tias tsis muaj cov piam thaj txaus hauv lub cev, cov kabmob tseem ceeb yuav raug kaw thaum kawg
Dab tsi yog cov cim tseem ceeb tseem ceeb rau tus menyuam muaj 10 xyoo?
Cov Cim Tseem Ceeb Hnub Nyoog Lub Plawv Ntshav Siab Ntshav 5-7 xyoo 65-138 80-115/40-80 8-10 xyoo 62-130 85-125/45-85 11-13 xyoo 62-130 95-135/45-85 14 -18 xyoo 62-120 100-145/50-90
Dab tsi yog tsib tus qauv tseem ceeb ntawm kev tswj tus kheej tus kab mob ntev?
Feem ntau ntawm cov kev tshawb fawb yog nyob hauv Asmeskas. Tsib tus qauv mob hnyav suav nrog Tus Qauv Kho Mob Ntev (CCM), Txhim Kho Kev Kho Mob Mob Ntev (ICIC), thiab Kev Tsim Kho Tshiab rau Kev Kho Mob Ntev (ICCC), Qauv Stanford (SM) thiab Zej Zog raws Kev Hloov Tus Qauv (CBTM). CCM yog tus qauv kawm ntau tshaj plaws
Dab tsi yog cov cim tseem ceeb tseem ceeb rau tus menyuam mos?

Vim li cas tus qauv ntawm hemoglobin tseem ceeb?
Hemoglobin. Hemoglobin muaj nyob rau hauv cov qe ntshav liab, uas ua tau zoo nqa oxygen los ntawm lub ntsws mus rau cov ntaub so ntswg ntawm lub cev. Hemoglobin kuj tseem pab thauj cov pa roj carbon dioxide thiab hydrogen ions rov qab mus rau lub ntsws. Hemoglobin lossis Hemoglobin tuaj yeem khi rau cov pa roj nitric oxide (NO) ntxiv rau O2
