Lub cell daim nyias nyias thiab nws lom lub luag hauj lwm

Tam sim no, rau ntau tus neeg nws yog tsis muaj daim card uas lub week yog ib qho tseem ceeb nyob rau hauv cov kev cai ntawm biochemical dab nyob rau hauv lub cell. Vim lom week kev txhawb los ntawm sab hauv homeostasis nyob rau hauv lub cell. Cell membrane vysokoizberatelno adjusts cov kev ceev ntawm allergic ntawm ntau yam lom tebchaw rau hauv lub cell, raws li zoo raws li txoj kev tawm ntawm enzymes thiab transporters. Ntxiv mus, cov qauv no muaj ib tug complex lom complex uas muab ib tug xaav, transformation thiab hloov lwm lub tsev ntawm cov ntaub ntawv los ntawm cov ib puag ncig mus rau hauv lub cell.

Lub cell daim nyias nyias yog ib tug qauv uas txwv tsis pub lub hlwb thiab subcellular organelles (lysosomes, mitochondria, Golgi apparatus , etc.). Txhua lub cell yog ib tug holistic system ntawm week lub tsev nrog tubular, cov hnab thiab tso tsheb hlau luam. Lub lom membrane - nyias paib (60-70%) glycoprotein thiab lipoprotein xwm. Nws yuav tsum muab sau tseg tias cov kab mob thiab cog hlwb , tsis zoo li cov tsiaj tsis muaj peev xwm hloov tau lawv lub zoo li lawv yog surrounded los ntawm ib tug tuab cell phab ntsa. Cell membrane tsob nroj lub cev muaj polysaccharides, cov kab mob ntawm monosaccharides, amino qab zib, lipids thiab cov amino acids.

Tus qauv ntawm lub cell daim nyias nyias.

Lub ntsiab Cheebtsam ntawm cell week yog lipids (60-70%) - phosphatidylcholine, phosphatidylethanolamine, sphingomyelin thiab roj uas txhaws taus. Cholesterol yog txuas mus rau lub lom membrane rigidity, li ntawd, daim nyias nyias nrog ib tug me me concentration ntawm cholesterol ntau dua ywj. membrane proteins uas hais lipoprotein thiab glycoprotein ceg (30-35%). Cell membrane nyob rau hauv ib tug me me npaum li cas tseem muaj carbohydrates raws li ib feem ntawm glycoproteins, glycolipids thiab glycosaminoglycans (5-10%). Tus qauv ntawm cell week thiab yog me tebchaw (nucleic acids, antioxidants, inorganic ions, coenzymes, etc.). Ntshav membrane yog zoo yam thiab muaj ib nrog rau cov intracellular daim nyias nyias ntawm lub endoplasmic reticulum (reticulum). Muaj pes tsawg leeg muaj xws li reticulum membrane granular thiab agranular endoplasmic reticulum, uas faib lub puab qhov chaw mus rau hauv ib tug plurality ntawm cell compartments. Nws yog ib yam uas tseem ceeb heev nyob rau hauv cov kev cai ntawm intracellular thauj ntawm yam thiab khiav ntawm metabolic dab.

Cov nuj nqi ntawm lub cell daim nyias nyias.

Cell week muab ib tug teeb meem muaj nuj nqi, uas manifests nws tus kheej nyob rau hauv daim ntawv ntawm cov xim, tswj metabolism nrog cov ib puag ncig. Los ntawm xim permeability rau hauv ib lub cell yuav nkag mus rau tsuas tshuaj ntawm ib tug tej yam loj.

Biomembrane thauj muaj nuj nqi muaj cov kev hloov ntawm cov as-ham rau hauv lub cell thiab tshem tawm ntawm zaum kawg metabolites therefrom. Lub cell daim nyias nyias muab kev koom tes nyob rau hauv kev tswj cov pom pH. Cov tebchaw uas tsis muaj peev xwm sawv ntawm tus ntoo khaub lig bilipidny txheej, lawv txeem los ntawm kev cov cab kuj cov nqaijrog, thiab los ntawm endocytosis. Lub passive hom transprorta tshuaj mus rau lub hlwb xws li diffusion. Lub active thauj tej yog nqa tawm nrog kev koom tes ntawm poov tshuaj ntsev twj tso kua mis.

Matrix membrane muaj nuj nqi los ntawm tej yam interposition thiab orientation ntawm daim nyias nyias proteins. Hauj lwm tseem ceeb nyob rau hauv kom tus neeg kho tshuab zog muaj cell phab ntsa, thiab cov tsiaj - intercellular substance. Lub receptor muaj nuj nqi yog ua vim lub xub ntiag ntawm tshwj xeeb cov nqaijrog uas laus mus rau lub cell daim nyias nyias.

Lub enzymatic muaj nuj nqi kev lom week txuam nrog daim nyias nyias cov nqaijrog thiab enzymes. Piv txwv li, lub ntshav week ntawm epithelial hlwb (epithelial hlwb ntawm txoj hnyuv) muaj digestive enzymes.
