Ngitshele amaqiniso athile nge-hemoglobin usebenzisa umbhalo onikeziwe njengesethenjwa
Context:I-hemoglobin (hemoglobin ngesiNgisi saseBrithani), esifushanisiwe i-Hb noma i-Hgb, iyi-metalloprotein equkethe i-oxygen-transport etholakala kumaseli abomvu egazi (ama-erythrocytes) cishe azo zonke izilwane ezinomgogodla (ngaphandle kwezinhlanzi zomndeni we-Channichthyidae) kanye nezicubu zezinye izilwane ezingenamgogodla. I-hemoglobin esegazini ithwala i-oxygen isuka ezithweni zokuphefumula (isib. Amaphaphu noma ama-gills) iye emzimbeni wonke (okusho izicubu). Lapho ikhipha umoya-mpilo ukuze ivumele ukuphefumula komoya ukuze kunikeze amandla okwenza imisebenzi yomzimba ngenqubo ebizwa ngokuthi ukuguquguquka komzimba. Umuntu ophile kahle une-12 kuya ku-20 amagremu e - hemoglobin kuwo wonke ama - ml ayi - 100 egazi.
1. Izinkomo I-hemoglobin/Hb/Hgb yi-metalloprotein ephethe i-oksijini equkethe insimbi ekhona egazini elibomvu (erythrocytes) cishe lazo zonke izilwane ezinomgogodla (ngaphandle kwezinhlanzi) umndeni Channichthyidae) kanye nezicubu zezilwane ezithile ezingenamgogodla 2. Izingelosi I-hemoglobin ithwala umoya- mpilo egazini lisuka emithambo yokuphefumula (isib. umzimba (isib. izicubu). 3. Izindaba Ezinhle I-metabolism ingamandla asetshenziselwa ukwenza imisebenzi yomzimba. I-hemoglobin ikhipha umoya-mpilo ukuvumela ukuphefumula kwe-aerobic. 4. Izidakamizwa Umuntu ophilile unama - 12 kuya ku - 25 amagremu e - hemoglobin kuwo wonke ama - ml ayi - 100 egazi.
