Lub cell hu ua suicidal bag?

Nws ua raws li "kev pov tseg" ntawm lub xovtooj los ntawm kev rhuav tshem cov khoom ntawm tes uas tsis xav tau ntxiv lawm nrog rau cov molecules lossis txawm tias cov kab mob uas tau noj los ntawm lub xovtooj.
Puas yog hu ua lub hnab suicidal ntawm tes teb?
Teb tiav: Lysosomes yog lub npe hu ua lub hnab suicidal ntawm tes vim tias nws muaj peev xwm ua kom nws cov cell uas nws muaj nyob. Nws muaj ntau cov enzymes hydrolytic uas yog lub luag haujlwm rau kev puas tsuaj.
Vim li cas lysosome thiaj li hu ua suicidal hnab ntawm tes?
Yog li, cov lus teb raug yog, "lysosomes hu ua 'lub hnab suicidal' ntawm cell vim lawv muaj hydrolytic enzymes thiab cov enzymes hydrolytic zom tag nrho cov khib nyiab ntawm tes. "
Lysosomes zom cov cell li cas?
Ntxiv rau qhov degrading molecules coj los ntawm endocytosis, lysosomes zom cov khoom tau los ntawm ob txoj kev: phagocytosis thiab autophagy (Daim duab 9.37). … Cov khoom loj li no tau coj mus rau hauv phagocytic vacuoles (phagosomes), uas tom qab ntawd fuse nrog lysosomes, ua rau digestion ntawm lawv cov ntsiab lus.
