Pinocytosis - ke eng see?

Limatlafatsi kena tikolohong hare seleng a bale litsenyehelo ea a sebetsang a lipalangoang, e leng e e-ba teng ke enzyme e khethehileng. Tabeng ena ho na le e hlophisitsweng, tse peli tse - pinocytosis le phagocytosis.

Kakaretso bath ya tshebetso

Pinocytosis - ke tsela bokahohleng la ho ja, e leng tšobotsi ea limela le phoofolo liseleng. mozindo lona larileng ka a kopana le limatlafatsi tse ngata li-cell ea foromo qhibiliha. Phagocytosis - tshebetso tšoanang, empa ho na le ba ananelang likaroloana tiileng.

E o tsejoa hore pinocytosis ke hlasimollang bohlokoa bakeng sa sebopeho sa lysosomes, le phagocytosis e beha holim 'a tshwaetso ea lisele ke likokoana-hloko. dithulaganyo tsena tse peli ba le e ngata ho tloaelehileng, kahoo ba ile ba ba atisa ho mmoho bitsoa - cytosis kapa endocytosis, pinocytosis ke esita le ho feta atile. Haeba ntho e, ka fapana le hoo, ba nkiloeng liseleng tse, joale e 'ngoe e bua ka exocytosis.

Ho ka akaretsang, re ka re hore pinocytosis - tshebetso ya absorption ea marotholi seleng ea mokelikeli.

thulaganyou e Features

Hona joale e lokela ho boleloa hore count ya li-cell ke mocheso itšetlehileng ka eona le ke keng tsa tšoareloa 2 ° C, 'me tlas'a bohato la inhibitors tshilong ya dijo tse kang fluoride sodium.

Ka pinocytosis thehoa hlomelang a manyenyane cytoplasm - pseudopodia, e kopane le e mong le e meng 'me oa aparela marotholi mokelikeli. Tabeng ena bubble li thehoa, tse arohane tloha lera seleng e le ho fallela ka cytoplasm e, ho retelehela ka vacuoles bitsoa pinosomy.

Hlokomela hore pinocytosis - e boetse ke phello ea lisele pepesehetse kokoana-hloko ea ho fanyeha. Tabeng ena, ho vesicles thehoa na vibrios. Ke mona moo ka linako tse ling o ile a pepesa ho ba sethaleng sa "undressing". Ha hapang limolek'hule kholoanyane lithethefatsi motho hape e ntse e feta, bubble sebopeho le invagination - vacuole, empa mochine oa ho tsamaisa ya lithethefatsi hase mahlonoko. Greater tšusumetso e ka absorption ea mahlahana diokobatsi ke sebopeho bona, fineness, 'me ho ba teng ha mafu pataganeng litho tshilong ya dijo - gastritis kapa colitis, ho etsa mohlala, peptic seso.

protheine reabsorption ka tubules le renal

Pinocytosis - e mochine mafolofolo tsa protheine reabsorption ka nephron proximal renal. Nakong ea protheine hae khomarelang ho ea moeling oa borashe. Sebakeng invaginated lera lena, ka tsela eo ha thehoa vial nang protheine molek'hule. Ha protheine e ka hare ea woman take bubble, e qala ho bola ka-amino acid, e leng o ile a oa ka lera basolateral ka mokelikeli kantle ho sele. Ho tloha ka ho tsamaisa joalo hloka matla, o bitsoa a sebetsang.

Ke habohlokoa ho hlokomela hore ho na le khopolo ea ho tsamaisa palo e kahodimodimo ea dintho hore ba ka mafolofolo reabsorbed. Tshebetso ena e amanang le tsamaiso ea palo e kahodimodimo mojaro lipalangoang. E hlaha ha palo ea dikgokelo, a be lumen tsa tubules le renal, leta bokgoni ba enzyme le liprotheine ho tsamaisa amehang phetiso ya.

Ka mohlala, u ka boela ua fella ka phytoteratology tsoekere reabsorption seo se etsahala ka tubule proximal matsoelintsoeke. Haeba dikahare tsa ntho e feta renal bokgoni tshebetso, e qala ho arohana le moroto (tsoekere e tloaelehileng sa lemoha).

Meaning of pinocytosis

Tšebetso ena e etsahala ka tubules le renal le epithelium mala. Boikarabelo ba hae ke absorption le reabsorption tsa metsoako tse ngata (ho akarelletsa le protheine le mafura a) hore ke ho hlokahala hore ho tshebetsong tlwaelehileng ea 'mele.

Ho feta moo, ha e ntse e feta pinocytosis metabolism ka leboteng capillary. Kahoo, limolek'hule tsa kgolo e ke ke phunyeletse ka pores likepe tse nyenyane tsa mali, tsamaisoa ke pinocytosis. Tabeng ena e capillary lera e invaginated lisele tse, ka tsela eo eaba ba etsa vacuole eo potolohileng le molek'hule. Ka lehlakoreng le leng ba gorole thulaganyou e fapaneng le e qala ho nka sebaka - emiocytosis.

E lokela ho ile a bolela hore pinocytosis - ke karolo ea bohlokoa ea ho tsamaisa a sebetsang a Ion le ho sebelisa. Hore ke mochine o ka sehloohong oa ho kenella ka hare ka tikoloho ka hare ya dintho phahameng limolek'hule ea lisele. Ho phaella moo, ke tsela e ka sehloohong ea ho kenella ka hare ea liphoofolo kapa semela likokoana-hloko ka seleng moamoheli.
