Thaum ntxov endosomes tsim kom muaj tubulovesicular network kis thoob plaws cortical cytoplasm ntawm tes. Thaum ntxov endosomes yog lub chaw sorting thawj hauv lub endocytic txoj hauv kev uas cov txheej txheem endocytosed tuaj yeem rov ua dua mus rau lub cell membrane lossis tsom mus rau kev puas tsuaj hauv lysosomes.
Ua li no, ua li cas thaum ntxov endosomes tsim?
Ib zaug cov kab mob endocytic vesicles muaj uncoated, lawv fuse nrog thaum ntxov endosomes . Thaum ntxov endosomes ces paub tab lig endosomes ua ntej fusing nrog lysosomes. Thaum ntxov endosomes paub tab nyob rau ntau txoj hauv kev daim ntawv lig endosomes . Lawv dhau los ua acidic feem ntau los ntawm kev ua haujlwm ntawm V-ATPase.
Ib yam li ntawd, endosomes thiab vesicles zoo ib yam? Endosomes yog cov txheej txheem sib khi hauv cov cell uas peb hu lub cev . Lawv tau tsim los ntawm kev tsim cov txheej txheem nyuaj uas tau paub ua ke ua endocytosis. Endosomes yog qhov tseem ceeb rau kev tswj cov khoom hauv thiab tawm ntawm lub cell. Lawv ua raws li ib ntus xwb lub cev rau kev thauj mus los.
Los ntawm qhov ntawd, qhov pom endosomes nyob qhov twg?
Endosomes yog cov vesicles membrane-bound, tsim los ntawm ib tsev neeg ntawm cov txheej txheem sib sau ua ke hu ua endocytosis, thiab pom hauv cytoplasm ntawm txhua tus tsiaj ntawm tes. Lub hauv paus txheej txheem ntawm endocytosis yog qhov rov qab ntawm qhov tshwm sim thaum exocytosis lossis cellular secretion.
Dab tsi yog qhov txawv ntawm cov endosomes thaum ntxov thiab lig?
1) Yog, pH yog ib qho ntawm sib txawv ntawm ib ntxov thiab lig endosome , tab sis nws tsis yog tib leeg xwb sib txawv . Thaum ntxov endosomes muaj cov twj pH tab sis tseem tsis tau muaj cov kua qaub hydrolases. Acid hydrolases raug xa mus rau lig endosomes . 3) Lysosomes zom cov organic molecules- protein, polysaccharides, lipid, thiab nucleic acids.

Nws puas zoo dua los kho thaum yav tsaus ntuj lossis thaum sawv ntxov?
Ib yam li txhua tus tub ntxhais kawm muaj qhov kev kawm tshwj xeeb, cov tub ntxhais kawm sib txawv tuaj yeem kawm tau zoo dua nyob rau lub sijhawm sib txawv ntawm hnub ntawd. Rau qee tus tub ntxhais kawm, tsom mus rau kev ua haujlwm hauv tsev kawm ntawv yooj yim dua thaum sawv ntxov thaum nruab hnub, thaum lwm tus yuav pom tias kev kawm thaum hmo ntuj ua haujlwm zoo dua rau lawv
Vim li cas kuv lub plab mob thaum kuv haus mis thaum sawv ntxov?
Cov neeg uas muaj lactose intolerance tsis tsim cov lactase txaus uas xav tau los zom cov lactose. Qhov no tuaj yeem ua rau xeev siab, mob plab, roj, tsam plab, thiab raws plab rau cov neeg uas tsis muaj lactose yog tias lawv noj lossis haus mis lossis khoom noj uas muaj lactose ntau
Thaum twg kuv yuav tsum noj Januvia thaum sawv ntxov lossis hmo ntuj?
Kuj hu ua: Januvia®; Janumet® (sib txuas ua ke
Qhov txawv ntawm qhov endosome thaum ntxov lig lig endosome thiab lysosome yog dab tsi?
1) Yog lawm, pH yog ib qho ntawm qhov sib txawv ntawm qhov ntxov thiab lig endosome, tab sis nws tsis yog qhov txawv xwb. Endosomes thaum ntxov muaj cov twj pH tab sis tseem tsis tau muaj cov kua qaub hydrolases. Acid hydrolases xa mus rau endosomes lig. 3) Lysosomes rhuav tshem cov organic molecules- proteins, polysaccharides, lipids, thiab nucleic acids
Leej twg yog tus txhawb nqa thaum ntxov ntawm kev ua haujlwm?
Paub rau: Leej Txiv ntawm Kev Kawm Psychology;
