Hemoglobin Synthesis . Hemoglobin synthesis xav tau kev sib koom tes ntau lawm hmo thiab lub ntiaj teb . Heme yog cov pab pawg neeg siv hluav taws xob uas ua kom muaj kev cuam tshuam hloov pauv ntawm cov pa los ntawm hemoglobin . Globin yog cov protein uas nyob ib puag ncig thiab tiv thaiv hmo molecule.
Hais txog qhov no, yuav ua li cas thiaj tsim tau hemoglobin?
Hemoglobin (Hb) yog synthesized nyob rau hauv ib tug complex series ntawm cov kauj ruam. Qhov heme yog synthesized nyob rau hauv ib tug series ntawm cov kauj ruam nyob rau hauv lub mitochondria thiab cytosol ntawm cov qe ntshav liab tsis paub qab hau, thaum lub globin protein qhov chaw yog synthesized los ntawm ribosomes hauv cytosol.
Tsis tas li, dab tsi yog qhov tseem ceeb rau kev tsim hemoglobin? Hemoglobin thiab Kev Ua Haujlwm ntawm Hlau. Hlau yog ib tseem ceeb keeb rau cov ntshav tsim. Kwv yees li 70 feem pua ntawm koj lub cev hlau muaj nyob hauv cov qe ntshav liab ntawm koj cov ntshav hu ua hemoglobin thiab hauv cov leeg nqaij hu ua myoglobin. Hemoglobin yog tseem ceeb rau kev xa cov pa oxygen hauv koj cov ntshav los ntawm lub ntsws mus rau cov ntaub so ntswg.
Ntxiv rau qhov no, hemoglobin yog dab tsi thiab nws txoj haujlwm?
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.
Dab tsi yog 3 hom hemoglobin?
Muaj ob peb ntau hom ntawm globin chains, npe hu ua alpha, beta, delta, thiab gamma. Li qub hom hemoglobin suav nrog: Hemoglobin A ( Hb A): ua txog li 95% -98% ntawm hemoglobin pom nyob rau hauv cov neeg laus; nws muaj ob txoj kev sib tw alpha (α) thiab ob beta (β) cov protein sib txuas.

Tus qauv tseem ceeb ntawm Hemoglobin yog dab tsi?
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 hemoglobin Dab tsi yog nws txoj haujlwm quizlet?
Hemoglobin yog tus. protein molecule nyob rau hauv cov ntshav liab uas nqa oxygen los ntawm lub ntsws mus rau lub cev cov ntaub so ntswg thiab xa carbon dioxide los ntawm cov ntaub so ntswg rov qab mus rau lub ntsws. Hemoglobin yog ua los ntawm plaub cov protein molecules (globulin chains) uas yog. txuas ua ke
Puas yog penicillin inhibit protein synthesis?
Penicillin, yog ib ntawm thawj cov tshuaj tua kab mob tau siv dav, tiv thaiv qhov kawg ntawm kev sib txuas sib txuas kauj ruam, lossis hloov pauv, hauv kev sib dhos ntawm macromolecule. Lwm hom tshuaj tua kab mob - tetracycline - tseem inhibits cov kab mob loj hlob los ntawm kev txwv cov protein synthesis
Hemoglobin yog dab tsi thiab yog vim li cas nws yog ib qho tseem ceeb protein?
Hemoglobin yog cov protein nyob hauv koj cov qe ntshav liab uas nqa oxygen mus rau koj lub cev thiab cov ntaub so ntswg thiab thauj carbon dioxide los ntawm koj lub cev thiab cov ntaub so ntswg rov qab mus rau koj lub ntsws. Yog tias qhov kev kuaj hemoglobin qhia tias koj qib hemoglobin qis dua li qub, nws txhais tau tias koj muaj cov qe ntshav liab tsawg (anemia)
Puas yog doxycycline inhibit protein synthesis?
Mechanism ntawm kev nqis tes ua. Doxycycline yog tshuaj tua kab mob dav dav. Nws tiv thaiv kev sib txuas ntawm cov kab mob protein los ntawm kev khi rau 30S ribosomal subunit, uas tsuas yog pom hauv cov kab mob
