- Thaum cov hlab ntsha raug mob, nws tso tawmthrombokinase. Qhov no nrog rau ntau yam tso tawm los ntawm cov platelets hloov prothrombin rau thrombin, uas yog cov ntaub ntawv tsis muaj zog thiab tsis muaj zog ntawm cov enzyme feem.
Qhov twg yog thrombokinase synthesized?
saib kuj Clotting factors General: Factor 10 (factor X), tseem hu ua Stuart-Prower factor lossis thrombokinase, yog ib qho enzyme ntawm coagulation cascade. Nws yog ib qho serine endopeptidase (protease pawg S1). Factor X yog synthesized nyob rau hauv lub siabthiab xav tau vitamin K rau nws cov synthesis.
YPuas yog prothrombin activator thiab thrombokinase tib yam?
Prothrombin thrombin 3. Fibrinogen fibrin 2. Ua kom cov prothrombin los ntawm thrombokinase ua raws li cov txheej txheem ntawm cov tshuaj tiv thaiv unimolecular, thiab cov concentration ntawm thrombokinase txiav txim siab thawj tus nqi. Los ntawm qhov kev sib txheeb thrombokinase tau ntsuas, thiab qhov ua kom nws ua ntej tau teev tseg.
YPuas yog thrombokinase yog ib qho tshuaj tiv thaiv coagulant?
Zaj. Kev sib raug zoo ntawm anticoagulant heparintau tshawb xyuas nrog thrombotropin, prothrombokinase, thrombokinase thiab calcium. Nws tau pom tias heparin thiab thrombotropin yog nyob rau hauv kev sib raug zoo antagonistic. Prothrombokinase thiab thrombokinase txo cov kev ua ntawm heparin rau tib yam.
Yuav ua li cas hloov prothrombin rau thrombin?
Prothrombin hloov mus ua thrombin los ntawm qhov ua kom ntshav khov hu ua yam X lossisprothrombinase; thrombin ces ua rau hloov fibrinogen, kuj muaj nyob rau hauv plasma, mus rau hauv fibrin, uas, ua ke nrog platelets los ntawm cov ntshav, tsim ib tug txhaws (ib txoj kev hu ua coagulation).
