Seleng lera le mosebetsi lona tsa likokoana-hloko

Hona joale, ho batho ba bangata ke ho sephiri hore lera le ke elements senotlolo ka molao oa tsamaiso ea dithulaganyo skeletal ka seleng. Ka lebaka lera la likokoana-hloko tshehetswa ke homeostasis hare ka har'a sele. Cell lera vysokoizberatelno fetola lebelo la ho kenella ka hare tsa metsoako e sa tšoaneng tsa likokoana-hloko ka seleng, hammoho le tsela ea ho tsoa enzyme le ba tsamaiso ea lipalangoang. Ho feta moo, sebopeho sena se na le rarahaneng tsa likokoana-hloko e rarahaneng eo e fana ka maikutlo a, ntlafalo le phetiso ya tlhahisoleseding ho tswa tikoloho ka seleng.

The lera seleng e ke sebopeho e thibela lisele le organelles subcellular (lysosomes, mitochondria, Golgi sethusathuto , joalo-joalo). Sele ka 'ngoe e ka tsamaiso ho phethahetseng ka hohlehohle tsa lera la hahoa le tubular, mekotla le litanka. The lera likokoana-hloko - lipoleiti tšesaane (60-70%) glycoprotein le lipoprotein tlhaho. Re lokela ho hlokomela hore baktheria le dimela lisele tse , ho fapana le liphoofolo tse ha ba khone ho fetola sebopeho bona ha ba ntse ba pota-potiloe ke e teteaneng leboteng ka seleng. Cell lera semela 'mele e na le polysaccharides, libaktheria tsa monosaccharides, amino tsoekere, lipids le-amino acid.

Sebōpeho sa sele lera.

Metsoako e ka sehloohong ea lera la li-cell ke lipids (60-70%) - phosphatidylcholine, phosphatidylethanolamine, sphingomyelin le k'holeseterole e. K'holeseterole e khomaretse le tsa likokoana-hloko lera se tenyetsehe, kahoo le lera ka ea mahloriso e nyenyane ea k'holeseterole e eketsehileng rekere. liprotheine lera tse hlahisoang lipoprotein le mehahong glycoprotein (30-35%). Cell lera ka e nyenyane e boetse e na lik'habohaedreite le karolo ea glycoproteins, glycolipids le glycosaminoglycans (5-10%). Sebōpeho sa lera la sele le tse metsoako nyenyane (acid nucleic, antioxidants, ions inorganic, coenzymes, joalo-joalo). Lero la mali lera tse haufi-ufi amanang le ba bohlokoa le lera la intracellular tsa reticulum endoplasmic (reticulum). Sebopeho se akarelletsa reticulum lera granular le agranular endoplasmic reticulum, eo arola sebaka ka hare ka ho plurality ea liphaposi seleng. Ke ea bohlokoa haholo ka molao oa tsamaiso ea lipalangoang intracellular ya dintho le phallo ea dithulaganyo tshilong ya dijo.

Mosebetsi ya lera seleng.

Cell lera la fana ka mokoallo mosebetsi, e bontša ka boeona e ka sebōpeho sa khetha, laoloa metabolism le tikoloho. Ka khetha e lumellang metsi ho kena ka seleng ka kenya dintho feela ea boholo itseng.

Biomembrane tsamaisa mosebetsi fana ka phetiso ya limatlafatsi ka sele le ho tlosa metabolites qetela therefrom. The lera seleng ea ameha boloka ph homolog. Tseo metsoako eo ha ea nang le bokhoni ea lera le sefapano se bilipidny, ba phunyeletse ka liprotheine itseng microcyteme, 'me ke endocytosis. The etseng letho mofuta transprorta dintho ka lisele tse kenyeletsa diffusion. The lipalangoang mafolofolo dintho o etsoang tsoa le ho kenya letsoho ha pompo potassium-sodium.

Matrix lera mosebetsi bakoang ke itseng interposition le ho tlwaetsa liprotheine lera. karolo ea bohlokoa ka ho etsa bonnete ba mesebetsi phetha molao na mabota seleng, le liphoofolo - intercellular ntho. Mosebetsi receptor o etsoa ka lebaka la ho ba teng ha liprotheine tse ikhethang tseo ba localized ho lera seleng.

The enzymatic mosebetsi wa lera la likokoana-hloko tse amanang le liprotheine lera le potlakisang tsebetso ea lik'hemik'hale. Ka mohlala, lero la mali lera la lisele tse epithelial (epithelial lisele tsa intestine le) e na le tshilong ya dijo enzyme.
