Pinocytosis - chii ichi?

Zvinovaka muviri kupinda womukati muchitokisi zvakatipoteredza tichiregeredza basa chokufambisa, izvo wakapindwa chaiwo makemikari. Muchiitiko ichi pane pezvakaitwa maviri - pinocytosis uye phagocytosis.

General hunhu kwacho

Pinocytosis - inzira inoshanda kudya, izvo runozivisa chirimwa uye mhuka masero. Chaizvoizvo Its nhema neVadzidzi sero zvinovaka muviri ari yakanyauka muchimiro. Phagocytosis - yakafanana muitiro, asi paine yokuita zvinoitwa zvakasimba inoramba.

Zvinozivikanwa kuti pinocytosis inokosha anotikurudzira kuti paumbwe lysosomes, uye phagocytosis zvinoiswa pamusoro chirwere masero nemavhairasi. pezvakaitwa maviri aya ane zvakawanda, saka vari kazhinji pamwe kunzi - cytosis kana endocytosis, pinocytosis chiri kunyanya kukura. Kana fuma, nekusiyana, zvinobviswa mumasero, ipapo munhu anotaura exocytosis.

Aunganidze pamwe, tinogona kutaura kuti pinocytosis - inofanira Absorção de Água muchitokisi emura mumate.

gadzira Features

Zvino zvinofanira kutaurwa kuti sero count iri tembiricha zvaanoda uye haagoni yakaitirwa 2 ° C, uye pasi zvinoitwa metabolic FIs akadai yavaibvisa fluoride.

In pinocytosis vakaumba outgrowths cytoplasm - pseudopodia, izvo batanidza nemumwe uye envelop nemvura mumate. Panyaya iyi matema vari kuumbwa, izvo akaparadzaniswa muchitokisi Kamudzira uye kuti tama kubudikidza cytoplasm, akatendeuka kupinda vacuoles anonzi pinosomy.

Cherechedza kuti pinocytosis - ndiyewo mugumisiro masero pachena kuti utachiwana kuturika. Panyaya iyi, iyo yakaumbwa vesicles ane vibrios. Zviri pano kuti vari dzimwe nguva pachena kuti padariro "undressing". Kana akatora makuru mamorekuru zvinodhaka munhu uyewo inopfuura rouchenjeri inotungamirwa uye invagination - vacuole, asi mashandiro pakufamba zvinodhaka hakukoshi. Greater simba pamusoro Absorção de Água ose pharmacological yomuchipatara ndiko chimiro chavo, fineness, uye kuvapo concomitant zvirwere Inosanganisa nhengo - gastritis kana colitis Somuenzaniso, peptic urikanwi.

mapuroteni reabsorption ari renal tubules

Pinocytosis - chinoshingaira mashandiro mapuroteni reabsorption ari proximal renal nephron. Panguva mapuroteni ake anobatanidza kusvikira bhurasho kumuganhu. Munzvimbo invaginated Kamudzira ichi, nokudaro kuumbwa chinu chine puroteni Morekuru. Kana puroteni riri mukati sefuro, rwunotanga anoora kupinda amino acids, vakazochinja kuwira kuburikidza basolateral Kamudzira kupinda extracellular mvura. Sezvo zvekufambisa kwakadaro kunoda simba, kunonzi tichishingaira.

Zvinokosha kucherechedza kuti pane pfungwa kunonyanyisa chokufambisa ose zvinhu zviri kushingaira reabsorbed. Izvi Rinobatanidzwa ne kufadza mutoro zvokufambisa zvavose. It kunoitika apo uwandu kubatana, vakapinda lumen ari renal tubules, akapfuudza nezvaanogona pakati makemikari uye yokufambisa mapuroteni vaibatanidzwa kuchinjwa.

Somuenzaniso, unogona zvakare kuguma havachanyatsogoni shuga reabsorption kuti rikaitika proximal tubule ichitenderera. Kana zviri pafuma kwazvo renal dzichipfekeka nezvaanogona, rwunotanga kuparadzana weti (kuipa shuga haana dzakaonekwa).

Meaning of pinocytosis

Izvi zvinoitika muna renal tubules uye intestinal epithelium. Ndiye anokonzera Absorção de Água uye reabsorption pakati yeimwe zhinji (kusanganisira mapuroteni uye mafuta) kuti chinodiwa kuti dzose kushanda muviri.

Uyezve, kana inopfuura pinocytosis muviri kubudikidza rirambe richibvira rusvingo. Saka, mamorekuru guru risingagoni kupinda kuburikidza pores zviduku midziyo ropa, yaitakurwa pinocytosis. Panyaya iyi rirambe richibvira Kamudzira iri invaginated masero, nokudaro wezvamatongerwe vacuole iyo runopoteredza Morekuru. Pakatarisana divi keji wakatarisana muitiro kunotanga kuitika - emiocytosis.

Zvinofanira kutaurwa kuti pinocytosis - zvinokosha chezvinonhuwira vanoshingaira Ion chokufambisa uye kushandisa. Kuti ndicho chikuru mashandiro kuti kupinda munzvimbo womukati ezvinhu mukuru samolecular zvinhu nemasero. Uyezve, ndiyo nzira mikuru kupinda mhuka kana kurima mavhairasi ari musero.
