Plasma yog nyob rau hauv txhua tus.
Plasma ua nce kwv yees li 55% ntawm tag nrho cov ntshav ntim thiab yog tsim los ntawm cov dej feem ntau (90% los ntawm ntim) ntxiv rau yaj cov proteins, qabzib, cotting yam, mineral ions, cov tshuaj hormones thiab carbon dioxide.
Kuj paub, dab tsi yog tsib yam tseem ceeb ntawm plasma?
Plasma Cheebtsam. Plasma muaj li ntawm 90 feem pua ntawm cov dej, nrog 10 feem pua yog ua los ntawm ions, cov proteins , yaj cov pa , nutrient molecules, thiab khib nyiab. Cov cov proteins hauv plasma suav nrog cov tshuaj tiv thaiv cov proteins , coagulation yam, thiab cov cov proteins albumin thiab fibrinogen uas tswj cov ntshav osmotic siab.
Kuj Paub, plasma nyob qhov twg? Ib yam li ntawd, ntshav ntshav muaj ntau txhiab tus proteins uas tseem ceeb heev rau peb lub cev muaj peev xwm ua haujlwm. Albumin yog qhov ntau tshaj ntawm cov no. Nws yog ua hauv daim siab thiab khaws cov kua dej hauv koj cov hlab ntsha (thiab tawm ntawm koj lub cev cov ntaub so ntswg), nrog rau nqa cov tshuaj tseem ceeb hauv koj cov ntshav.
Ntawm no, ntshav plasma yog dab tsi?
Cov khoom ntawm ntshav ntshav yog dej 92%, yaj protein 8%, qabzib, amino acids, vitamins, minerals, urea, uric acid, CO2, cov tshuaj hormones, tshuaj tiv thaiv. Plasma nqa cov khoom yaj xws li qabzib, amino acids, minerals, vitamins, ntsev, carbon dioxide, urea, thiab cov tshuaj hormones. Nws kuj nqa lub zog cua sov.
Dab tsi yog plasma hauv tib neeg lub cev?
Ntshav ntshav ntshav yog cov kua daj daj ntawm cov ntshav uas tuav cov qe ntshav hauv cov ntshav tag nrho hauv kev ncua. Nws yog qhov ua kua ntawm cov ntshav uas nqa cov hlwb thiab cov proteins thoob plaws hauv lub cev lub cev . Nws ua li 55% ntawm lub cev tag nrho cov ntshav ntim.

Lub luag haujlwm ntawm plasma membrane proteins yog dab tsi?
Membrane cov nqaijrog yuav ua raws li enzymes rau kom tshuaj haum, ua raws li receptors rau tej molecules, los yog thauj ntaub ntawv thoob plaws hauv lub cell daim nyias nyias. Carbohydrates, los yog suab thaj, qee zaum pom txuas nrog cov proteins lossis lipids sab nraud ntawm lub cell membrane
Cov plasma membrane yog dab tsi?
Lub plasma membrane, tseem hu ua cell membrane, yog daim nyias nyias muaj nyob rau hauv tag nrho cov hlwb uas cais cov sab hauv ntawm lub cell los ntawm ib puag ncig sab nraud. Lub plasma membrane muaj ib tug lipid bilayer uas yog semipermeable. Lub plasma membrane tswj kev thauj cov khoom nkag mus thiab tawm ntawm lub cell
Dab tsi yog cov tails ntawm phospholipids ntawm cov plasma membrane muaj li ntawm?
Phospholipids yog ib chav kawm ntawm lipids uas yog ib feem tseem ceeb ntawm tag nrho cov cell membranes. Lawv tuaj yeem tsim cov lipid bilayers vim lawv cov yam ntxwv amphiphilic. Cov qauv ntawm cov phospholipid molecule feem ntau muaj ob hydrophobic fatty acid 'tails' thiab ib tug hydrophilic 'lub taub hau' uas muaj ib pab pawg neeg phosphate
Cov qauv thiab kev ua haujlwm ntawm plasma membrane yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm plasma membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Ua los ntawm cov phospholipid bilayer nrog cov proteins embedded, plasma membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm cov hlwb
Dab tsi yog plasma membrane luv txhais?
Plasma Membrane Txhais. Lub plasma membrane ntawm ib lub xovtooj ntawm tes yog lub network ntawm lipids thiab cov proteins uas tsim cov ciam teb ntawm cov ntsiab lus ntawm tes thiab sab nraud ntawm lub cell. Nws kuj tseem hu ua cell membrane. Nws yog semi-permeable thiab tswj cov ntaub ntawv uas nkag mus thiab tawm ntawm lub cell
