Lysosomes tawg macromolecules rau hauv lawv cov khoom siv, uas tom qab ntawd rov ua dua. Cov organelles daim nyias nyias muaj ntau yam enzymes hu ua hydrolases uas zom tau cov proteins, nucleic acids, lipids, thiab complex suab thaj. Lub lumen ntawm lysosome yog acidic ntau dua li cytoplasm.
Yuav ua li cas organelles ua haujlwm nrog lysosomes?
Lysosomes vam khom enzymes tsim hauv cytosol thiab endoplasmic reticulum. Lysosomes siv cov enzymes (acid hyrolases) los zom zaub mov thiab 'kho tawm cov khib nyiab.
Lysosome cuam tshuam nrog lwm cov organelles li cas?
Kev tshawb fawb tsis ntev los no qhia tias lysosomes yog cov organelles uas khaws cov enzymes hydrolytic hauv lub xeev tsis ua haujlwm. Lub kaw lus yog qhib thaum lub lysosome fuses nrog lwm cov organelle los tsim ib tug 'hybrid qauv'qhov twg cov tshuaj digestive tshwm sim nyob rau hauv acid (txog pH 5.0) tej yam kev mob.
Puas lysosomes fuse nrog lwm cov organelles?
Cov ntsiab lus tseem ceeb. Lysosomes yog dynamic organelles uas tau txais kev nkag mus rau hauv daim nyias nyias los ntawm txoj kev secretory, endocytic, autophagic thiab phagocytic txoj kev. Lawv tuaj yeem fuse nrog cov ntshav plasma. Live-cell imaging tau qhia tias lysosomes cuam tshuam nrog lig endosomes los ntawm 'kiss-and-run' cov xwm txheej thiab los ntawm fusion ncaj qha.
Lub luag haujlwm tseem ceeb ntawm lysosomes yog dab tsi?
Lysosomes ua haujlwm raws li lub plab zom mov ntawm tes, ua haujlwmob qho tib si rau degrade cov khoom coj los ntawm sab nraud ntawm tes thiab zom cov khoom siv ntawm tes nws tus kheej.
