Ib endosome yog daim nyias nyias-khi rau hauv ib lub cell eukaryotic. Nws yog ib qho organelle ntawm lub cov kab mob endocytic membrane thauj txoj hauv kev los ntawm trans Golgi network. Molecules kuj raug thauj mus rau endosomes los ntawm trans Golgi network thiab txuas ntxiv mus rau lysosomes lossis rov ua dua rov qab mus rau Golgi apparatus.

Piv txwv li, endosome ua 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 cov xovtooj ntawm tes thiab thauj cov ntaub ntawv los ntawm Golgi mus rau lysosome los yog ua vacuole.

Tsis tas li ntawd, qhov 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.

Xav txog qhov no, endosomes muaj dab tsi?

Endosomes yog tshwj xeeb tshaj yog cov kab mob hauv lub cev. Lawv tswj kev lag luam ntawm cov protein thiab lipid ntawm lwm qhov chaw sib cais ntawm cov secretory thiab cov kab mob endocytic txoj hauv kev, tshwj xeeb yog cov ntshav membrane Golgi, trans-Golgi network (TGN), thiab vacuoles/lysosomes.

Endosomes nyob qhov twg?

Endosomes yog daim nyias nyias-khi vesicles, tsim los ntawm tsev neeg nyuaj ntawm cov txheej txheem sib sau ua ke hu ua endocytosis, thiab pom hauv cytoplasm ntawm txhua tus tsiaj ntawm tes.
