Qhov sib txawv tseem ceeb ntawm phagocytosis thiab pinocytosis yog phagocytosis yog ib hom endocytosis uas uptakes solids los ntawm cov plasma membrane mus rau lub cell thaum pinocytosis yog lwm hom endocytosis uas uptakes kua xws li solutes thiab me me molecules los ntawm lub plasma membrane mus. lub cell.
Endocytosis yog ib txoj hauv kev uas cov hlwb tau txais macromolecules thiab lwm cov khoom raug tshem tawm nrog rau cov khoom ntawm tes, macromolecular aggregates, thiab cov khoom txawv teb chaws rau hauv lub cell. Exocytosis yog qhov sib txawv ntawm cov txheej txheem endocytosis uas cov hlwb cais cov tshuaj los ntawm cov hlwb. Exocytosis feem ntau tshwm sim hauv cov cell secretory. Muaj ob hom endocytosis raws li qhov xwm txheej ntawm cov khoom uas tau coj mus rau hauv cov hlwb nyob. Lawv yog phagocytosis thiab pinocytosis. Lub mechanism siv nyob rau hauv ob qho tib si txheej txheem yog tib yam. Lawv tsim cov vesicles nyob ib puag ncig cov ntaub ntawv txhawm rau coj lawv mus rau hauv. Ob txheej txheem yog cov txheej txheem nquag. Li no, koj tuaj yeem soj ntsuam mitochondria nyob ze ntawm qhov chaw uas cov txheej txheem no tshwm sim.
Phagocytosis yog dab tsi?
Phagocytosis, tseem hu ua cell noj, yog kev noj cov khoom loj dua li ntawm 0.5µm hauv txoj kab uas hla los ntawm endocytosis. Hauv qhov no, plasma membrane fuses rau pem hauv ntej thiab nyob ib puag ncig cov khoom nyob ze ntawm lub xov tooj ntawm tes los tsim cov phagocytic vesicles hu ua phagosomes. Tom qab ntawd lysosomes tuaj thiab fuse nrog cov phagosomes thiab tso lawv cov plab zom mov kom zom cov ntsiab lus hauv phagosomes.
Daim duab 01: Phagocytosis
Phagocytosis yog txheej txheem uas feem ntau protozoa suav nrog amoeba engulf thiab zom lawv cov tsiaj. Hauv cov tsiaj siab dua, neutrophils thiab macrophages ntawm lub cev tiv thaiv kab mob siv cov txheej txheem no los tiv thaiv lub cev txawv teb chaws xws li kab mob, kab mob, cov plua plav, cov hlwb tuag, qhov chaw ntawm tes, thiab lwm yam khoom pov tseg.
YPinocytosis yog dab tsi?
Pinocytosis yog kev noj cov tee ntawm cov kua dej ntxiv nrog rau cov khoom me me. Vim yog qhov xwm txheej ntawm cov khoom siv hauv pinocytosis, nws yog ib hom kev haus dej ntawm tes. Nws pab kom noj cov tshuaj tseem ceeb xws li insulin thiab lipoproteins hauv cov ntsiab lus.
Daim duab 02: Pinocytosis
Tsis tas li ntawd, ions, suab thaj, thiab amino acids kuj nkag mus rau ntawm tes los ntawm txoj kev no. Nyob rau hauv cov ntaub ntawv no, thawj extracellular kua nrog feeb hais adheres rau tej receptors nyob rau hauv lub cell membrane. Tom qab ntawd, cov plasma daim nyias nyias ntawm qhov chaw tshwj xeeb invaginates thiab nyob ib puag ncig cov khoom kom tsim cov vesicles membrane-bounded hu ua pinosomes. Cov pinosomes ces txav mus rau hauv cytoplasm, thiab cov ntsiab lus raug tso tawm. Pinocytosis tuaj yeem pom ntau zaus hauv cov hlwb uas kab cov ntshav capillaries.
Dab tsi zoo sib xws ntawm Phagocytosis thiab Pinocytosis?
- Phagocytosis thiab pinocytosis yog ob hom endocytosis.
- Ob txoj hauv kev coj cov ntaub ntawv los ntawm cov ntshav plasma los ntawm kev tsim cov vesicles.
Qhov txawv ntawm Phagocytosis thiab Pinocytosis yog dab tsi?
Phagocytosis yog kev noj cov khoom loj dua li ntawm 0.5µm nyob rau hauv txoj kab uas hla, whereas pinocytosis yog kev noj cov tee ntawm cov kua dej ntxiv nrog rau cov khoom me me. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phagocytosis thiab pinocytosis. Feem ntau, phagocytosis yog ib qho cuab yeej rau kev tiv thaiv lub hom phiaj thaum pinocytosis yog ib txoj hauv kev coj cov khoom tseem ceeb rau hauv cov hlwb. Yog li, qhov no yog qhov sib txawv ntawm phagocytosis thiab pinocytosis.
Ntxiv mus, phagocytosis tsim cov vesicles hu ua phagosomes, whereas pinocytosis tsim cov vesicles hu ua pinosomes. Tsis tas li ntawd, tsis zoo li hauv pinocytosis, kev koom tes ntawm lysosomes tuaj yeem pom hauv phagocytosis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phagocytosis thiab pinocytosis. Cells uptake cov khoom siv xws li kab mob, plua plav, cellular qhov chaw, thiab lwm yam, los ntawm phagocytosis; li no, nws yog hom cell noj. Ntawm qhov tod tes, cell uptakes kua xws li ions, suab thaj, amino acids, me me molecules, thiab lwm yam, rau hauv hlwb los ntawm pinocytosis; yog li ntawd, nws yog hom kev haus ntawm tes. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phagocytosis thiab pinocytosis. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm phagocytosis thiab pinocytosis yog qhov pinocytosis feem ntau tshwm sim hauv cov cell hauv cov ntshav capillaries, thaum phagocytosis yog siv los ntawm cov qe ntshav dawb xws li neutrophils thiab macrophages, thiab protozoan.
Summary – Phagocytosis vs Pinocytosis
Phagocytosis thiab pinocytosis yog ob lub tswv yim uas cov hlwb siv cov khoom siv hauv cov plasma membrane. Qhov sib txawv tseem ceeb ntawm phagocytosis thiab pinocytosis yog nyob rau hauv cov ntaub ntawv coj mus rau hauv. Phagocytosis uptakes cov khoom siv thaum pinocytosis uptakes kua nrog rau cov kua. Tsis tas li ntawd, phagocytosis yog ib qho cuab yeej uas pab tiv thaiv kab mob thaum pinocytosis yog ib txoj hauv kev rau kev noj cov khoom hauv. Tsis tas li ntawd, thaum kawg ntawm phagocytosis, exocytosis tshwm sim; Txawm li cas los xij, exocytosis tsis tshwm sim hauv pinocytosis. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm phagocytosis thiab pinocytosis.
