1) Yog, pH yog ib qho ntawm qhov sib txawv ntawm qhov 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- cov protein, polysaccharides, lipid, thiab nucleic acids.
Kuj paub, qhov sib txawv ntawm endosome thiab lysosome yog dab tsi?
Lysosome yog acidic thiab nws muaj cov enzymes uas tuaj yeem ua rau cov kab mob puas. Endosome yog tsim nyob rau hauv daim nyias nyias ntawm lub golgi los yog nyob rau hauv lub plasma membrane. Raws li Kev Tshawb Fawb Xwm: cov ntawv tshawb fawb, haujlwm, cov ntaub ntawv thiab kev pabcuam. " Endosomes yog membrane-delimited intracellular transport carriers ".
Ib yam nkaus, qhov ua haujlwm ntawm endosome yog dab tsi? Endosomes yog cov khoom sib txawv ntawm cov organelles uas ua haujlwm hauv kev txheeb xyuas thiab xa cov khoom siv sab hauv los ntawm ntawm tes nto thiab lub thauj ntawm cov ntaub ntawv los ntawm Golgi mus rau lysosome los yog ua vacuole.
Ib sab saum toj no, puas endosomes lig dhau los ua lysosomes?
Thauj los ntawm lig endosomes rau lysosomes yog, nyob rau hauv essence, unidirectional, txij li thaum a lig endosome yog "haus" nyob rau hauv tus txheej txheem ntawm fusing nrog a lysosome . Yog li ntawd, soluble molecules hauv lumen ntawm endosomes yuav zoo li mus xaus rau hauv lysosomes , tshwj tsis yog lawv tau rov qab los hauv qee txoj kev.
Puas yog endosomes thiab vesicles tib yam?
Endosomes yog cov txheej txheem sib khi hauv cov cell uas peb hu cov hlab ntsha . 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.

Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
Dab tsi yog qhov ua haujlwm ntawm kev ncua lig lig lig?
