Hemoglobin . Hemoglobin muaj nyob hauv cov qe ntshav liab, uas muaj txiaj ntsig nqa oxygen los ntawm lub ntsws mus rau cov nqaij ntawm lub cev. Hemoglobin kuj tseem pab thauj cov pa roj carbon dioxide thiab hydrogen ions rov mus rau lub ntsws. Hemoglobin los yog Hemoglobin muaj peev xwm khi rau cov pa roj nitric oxide (NO) ntxiv rau O2.
Yog li, cov qauv ntawm hemoglobin cuam tshuam nrog nws txoj haujlwm li cas?
Hemoglobin muaj nyob rau hauv cov ntshav liab thiab nqa oxygen zoo ntawm lub ntsws mus rau cov ntaub so ntswg hauv lub cev. Nws kuj pab thauj cov hydrogen ions thiab carbon dioxide rov qab mus rau lub ntsws. Txhawm rau thauj cov pa oxygen kom zoo, kev lag luam ntawm plaub lub subunits hauv a hemoglobin molecule yuav tsum tau ua.
Ib tug kuj yuav nug, peb lub luag haujlwm ntawm hemoglobin yog dab tsi? Hemoglobin hauv cov ntshav nqa cov pa oxygen los ntawm lub ntsws lossis cov pa mus rau tag nrho lub cev (piv txwv li cov nqaij). Nyob ntawd nws tso cov pa oxygen tso rau kev ua pa aerobic txhawm rau muab lub zog rau lub zog kev ua haujlwm ntawm cov kab mob hauv cov txheej txheem hu ua metabolism.
Tom qab ntawd, tus qauv ntawm hemoglobin yog dab tsi?
Hemoglobin yog cov pa oxygen-transporting protein ntawm cov qe ntshav liab thiab yog globular protein nrog quaternary 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.
Vim li cas hemoglobin tseem ceeb rau lub cev xeem ntawv?
Vim tias nws nqa oxygen mus rau lub cev cell thiab nqa carbon dioxide tawm ntawm lub lub cev hlwb. * Nws nqa oxygen mus rau lub lub cev hlwb. * Nws nqa carbon dioxide tawm ntawm lub cev hlwb.

Thawj Cov Qauv Ntawm nws qib yooj yim tshaj plaws, hemoglobin yog ua 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
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
