Qhov sib txawv tseem ceeb ntawm endocytosis thiab phagocytosis yog qhov endocytosis yog cov txheej txheem ntawm kev noj cov teeb meem mus rau hauv lub cell los ntawm kev tsim cell membrane vesicles thaum phagocytosis yog txheej txheem ntawm kev noj cov khoom loj rau hauv lub cell los ntawm kev tsim phagosomes.
Endocytosis thiab phagocytosis yog ob txoj kev thauj khoom uas coj cov khoom mus rau hauv lub cell. Endocytosis yog ntawm peb pawg. Ntawm lawv, phagocytosis thiab pinocytosis yog ob hom ntau tshaj plaws. Tsis tas li ntawd, phagocytosis yog ib hom kab mob endocytosis. Nyob rau hauv ob qho tib si mechanisms, cov ntaub ntawv raug coj mus rau hauv lub vesicles. Cov khoom siv no suav nrog cov khib nyiab ntawm tes, enzymes, cov hlwb tuag, cov kab mob, cov tshuaj hormones, cov as-ham, thiab lwm yam. Cov txheej txheem rov qab ntawm endocytosis yog exocytosis, uas cuam tshuam nrog kev tshem tawm cov khoom ntawm lub xovtooj ntawm tes uas nyob hauv vesicles.
YEndocytosis yog dab tsi?
Endocytosis yog cov txheej txheem ntawm kev noj cov ntaub ntawv thiab cov kua dej rau hauv lub cell los ntawm kev kaw lawv hauv vesicles. Lub kaw lus ntawm cov khoom siv qhov chaw los ntawm thaj tsam ntawm cov plasma membrane uas pinches tawm mus rau hauv lub cell los ntawm kev tsim cov vesicle. Peb hom endocytosis yog phagocytosis, pinocytosis thiab receptor-mediated endocytosis. Yog li, phagocytosis cuam tshuam nrog cov khoom siv xws li cov khoom siv loj thaum pinocytosis yog raws li kev noj cov kua dej nrog rau nws cov tshuaj.
Daim duab 01: Endocytosis
Ntxiv mus, lub vesicle tsim thaum lub sij hawm phagocytosis yog hu ua phagosome, thiab nyob rau hauv pinocytosis, nws yog hu ua pinosome. Feem ntau, lub pinosome yog tsim los ntawm Clathrin-coated pits nyob rau hauv lub plasma membrane. Tab sis qee qhov ntawm txoj kev pinocytic tsis muaj clathrin-coated vesicles. Lub phagosome yog qhov sib piv loj dua li pinosome vim phagosome suav nrog cov khoom loj dua. Pinocytosis yog ib qho txheej txheem tshwm sim hauv yuav luag txhua lub hlwb ntawm lub cev.
Phagocytosis yog dab tsi?
Phagocytosis yog txheej txheem ntawm kev noj cov khoom loj rau hauv lub cell los ntawm kev tsim phagosomes. Yog li ntawd, nws yog ib daim ntawv ntawm endocytosis. Cov ntaub ntawv coj mus rau hauv lub cell raws li cov txheej txheem no suav nrog cov khib nyiab ntawm tes, cov kab mob xws li cov kab mob, cov hlwb tuag, cov plua plav, cov ntxhia me me, thiab lwm yam. Tsis tas li ntawd, feem ntau ntawm lub cev tiv thaiv kab mob xws li cov ntaub so ntswg macrophages, neutrophils thiab monocytes yog cov kws tshaj lij phagocytoses ua cov hlwb..
Daim duab 02: Phagocytosis
Lwm hom phagocytic hlwb muaj nyob hauv Kupffer hlwb hauv daim siab, pigmented epithelium ntawm lub qhov muag, Langerhans hlwb hauv daim tawv nqaij thiab microglia hauv lub hlwb. Feem ntau, phagocytosis yog kev tiv thaiv mechanism. Yog li, nws koom nrog hauv kev rhuav tshem cov kab mob nkag los ntawm kev nkag mus rau hauv phagosomes thiab tom qab ntawd rhuav tshem hauv lub cell. Ib qho kev ua lytic tshwm sim nyob rau hauv lub cell uas ib tug lysosome khi rau phagosome thiab tso tawm lytic enzymes los rhuav tshem cov engulfed pathogen / khoom teeb meem. Thiab, cov qauv no hu ua phagolysosome.
Dab tsi zoo sib xws ntawm Endocytosis thiab Phagocytosis?
- Ob leeg endocytosis thiab phagocytosis yog ob lub tswv yim koom nrog kev noj cov khoom rau hauv lub cell.
- Ob lub tshuab tsim vesicles rau kev thauj mus los.
Qhov txawv ntawm Endocytosis thiab Phagocytosis yog dab tsi?
Kev nce ntawm cov ntaub ntawv los ntawm ib puag ncig extracellular mus rau hauv lub cell tshwm sim ntawm ob lub tshuab; endocytosis thiab phagocytosis. Endocytosis, qhov tseem ceeb, cuam tshuam nrog kev noj cov kua dej lossis tshem tawm cov khoom mus rau hauv lub cell. Phagocytosis suav nrog kev noj cov khoom me me rau hauv lub cell. Qhov no yog qhov sib txawv tseem ceeb ntawm endocytosis thiab phagocytosis. Txawm li cas los xij, phagocytosis yog ib hom endocytosis.
Hauv qab infographic nthuav tawm qhov sib txawv ntawm endocytosis thiab phagocytosis piv.
Summary – Endocytosis vs Phagocytosis
Ob leeg endocytosis thiab phagocytosis yog ob lub tswv yim uas koom nrog kev noj cov khoom rau hauv lub cell. Qhov sib txawv tseem ceeb ntawm endocytosis thiab phagocytosis yog qhov endocytosis yog cov txheej txheem ntawm kev noj cov teeb meem thiab kua dej rau hauv lub cell los ntawm kev tsim cov cell membrane vesicles thaum phagocytosis yog cov txheej txheem ntawm kev noj cov khoom loj rau hauv lub cell los ntawm kev tsim phagosomes. Ob hom kab mob endocytosis yog phagocytosis thiab pinocytosis. Phagocytosis cuam tshuam txog kev noj cov khoom xws li cov khoom siv loj thaum pinocytosis yog raws li kev noj cov kua dej nrog rau nws cov kua. Feem ntau, phagocytosis yog kev tiv thaiv mechanism. Yog li nws yog siv los rhuav tshem cov kab mob nkag los ntawm kev nkag mus rau hauv phagosomes thiab tom qab ntawd rhuav tshem hauv lub cell. Qhov no qhia txog qhov sib txawv ntawm endocytosis thiab phagocytosis.
