Pinocytosis - waxa uu yahay waxan?

Nafaqooyinka galaan deegaanka cell gudaha for kharash ku firfircoon gaadiidka, taas oo ka soo qayb galay ensaymes gaar ah. Xaaladdan oo kale, waxaa jira laba hannaan - pinocytosis iyo phagocytosis.

dabeecad guud ee geedi socodka

Pinocytosis - waa hab universal cunitaankii, taas oo caan ku ah dhirta iyo xayawaanka unugyada. Its nuxurka been xiriir la nafaqooyinka cell qaab kala diri ee. Phagocytosis - habka la mid ah, laakiin waxaa jira nuugo qayb ka adag.

Waxaa la og yahay in pinocytosis waa heshaa muhiim u ah formation of lysosomes, iyo phagocytosis baa cudurka unugyada dhigay by fayrasyada. Labadan hababka badan ee caadiga ah, sidaa daraaddeed waxaa inta badan si wadajir ah loo yaqaan - cytosis ama endocytosis, pinocytosis waa ka sii baahay. Haddii walaxda, on lid ku ah, waxaa ka soo jeeda unugyada, ka dibna mid ka mid ah ku hadla ee exocytosis.

Isku soo duuboo, waxaan dhihi karaa pinocytosis in - geeddi-socodka ah ee nuugista oo ka mid ah dhibco dareere ah unug.

Features habka

Haddaba waxaa la sheegay in tirada unugyada waa heerkulka ku tiirsan oo aan la qaban karaa 2 ° C, iyo hoos tallaabada of inhibitors dheefshiidka, sida fluoride sodium.

In pinocytosis sameeyay outgrowths cytoplasm - pseudopodia, taas oo ku milmaan kasta oo kale oo dabooli ah dhibco dareere ah. Xaaladdan oo kale naqas loo sameeyay, kuwaas oo loo kala soocay oo ka xuub cell iyo si ay u haajiraan iyada oo cytoplasm ah, bedalayo vacuoles yeedhay pinosomy.

Fiiro gaar ah pinocytosis in - Sidoo kale waa natiijada unugyada bandhigi ganaax fayraska. Xaaladdan oo kale, ka kiishka ku jira sameeyay vibrios. Waxaa halkan waa in ay mararka qaar soo if-yada ee "bixinta dharka". Marka qabsaday taagoo weyn daroogada shakhsi sidoo kale lagu tiriyo ee formation xumbo iyo invagination - vacuole, laakiin hab ay of gaadiidka daroogada ma aha muhiim ah. saameyn weyn ku nuugista ee wakiilada pharmacological waa qaab, fineness, iyo jiritaanka cudurada saameen ah xubnaha dheefshiidka - gastritis ama ulcerös, tusaale ahaan, boog ulcer.

nuugay protein ee tubules renal

Pinocytosis - hab firfircoon nuugay protein in nephron ku proximal kelyaha. Intii uu protein qabsadey soohdinta burushka. In meel invaginated xuub this, sidaas sameeyay weelka ay ku jirto Britain protein ah. Marka protein waa gudaha xumbo, wuxuu bilaabaa inuu cawisa galay acids amino, taas oo markii danbe u dhici dhex xuub basolateral dareeraha extracellular. Tan iyo gaadiidka sida u baahan tahay tamar, waxa la yidhaahdaa waa firfircoon.

Waxaa xusid mudan in uu jiro fikrad ah gaadiidka ugu badan ee walxaha in si firfircoon reabsorbed. Nidaamkan waxaa la xidhiidha nidaamka gaadiidka load ugu badnaan. Waxay dhacdaa marka tirada xidhiidhada, fuuleen ku Lumen ah tubules kelyaha, ka badato awoodaha of falgalka iyo borotiinada gaadiidka ku lug leh kala iibsiga.

Tusaale ahaan, waxaad sidoo kale waxay keeni kartaa in loo nuugay glucose oo yaraada in dhacdaa tubule ku proximal loogu fuuli jiray. Haddii content walax ka badan awoodooda functional kelyaha, wuxuu bilaabaa in ay kala kaadida (glucose caadiga ah lama dareemo).

Macnaha pinocytosis

geedi socodka waxa uu ka dhacayaa ay tubules kelyaha iyo epithelium xiidmaha. Wuxuu mas'uul ka yahay nuugista iyo nuugay xeryahooda badan (oo ay ku jiraan protein iyo baruurta) in uu yahay lagama maarmaan u ah hawlaha caadiga ah ee jidhka.

marka weliba, maraa shiid pinocytosis derbiga gaddoonka ah. Sayidka, taagoo waaweyn oo ma geli karto iyada oo daloolada marinnada dhiigga yar, gaadiid by pinocytosis. Xaaladdan oo kale xuub gaddoonka la invaginated unugyada, oon la xirrira vacuole ah oo ku wareegsan Britain ee. On dhinaca ka soo horjeeda geedi socodka qafis horjeeda bilaabaa inuu ka dhaco - emiocytosis.

Waa in sidoo kale lagu xusay in pinocytosis - waa qayb muhiim ah oo gaadiidka ra'iyi firfircoon iyo codsan. In ay tahay hab ay ugu muhiimsan ee wax lays geliyey deegaanka gudaha ee walxaha kelli sare ee unugyada. Intaa waxaa dheer, waa sida weyn ee wax lays of fayrusyada xoolaha ama warshad in gacanta ciidanka.
