Qhov sib txawv tseem ceeb ntawm phagolysosome thiab phagosome yog phagolysosome yog lub cev cytoplasmic tsim los ntawm kev sib xyaw ntawm phagosome nrog lysosome. Meanwhile, phagosome yog ib lub vesicle tsim nyob ib ncig ntawm cov hais engulfed los ntawm ib tug phagocytic cell thaum phagocytosis.
Phagocytosis yog ib qho kev tiv thaiv uas siv rau hauv qee lub hlwb lossis cov kab mob kom tshem tawm cov khoom txawv teb chaws ntawm lub cev. Phagocytes yog cov hlwb uas ua rau phagocytosis. Phagocytes yog hom qe ntshav dawb, tshwj xeeb tshaj yog, neutrophils, monocytes thiab macrophages muaj nyob hauv cov ntshav. Cov hlwb no tiv thaiv lub cev los ntawm kev kuaj xyuas cov khoom txawv teb chaws xws li cov kab mob, co toxins, tuag thiab tuag somatic hlwb, thiab lwm yam. Tom qab ntawd phagocytes engulf thiab rhuav tshem lawv. Phagocytosis yog ib hom kab mob endocytosis. Los ntawm phagocytosis, cov khoom uas muaj nyob rau hauv cov qauv hu ua phagosome. Thaum lawv raug daig hauv phagosome, lawv sib txuas nrog lysosomes thiab tsim phagolysosomes. Tom qab ntawd siv cov lysosome hydrolase enzymes, cov khoom hauv phagosome yog degraded thiab puas.
Phagolysosome yog dab tsi?
Phagolysosome yog cytoplasmic vesicle tsim los ntawm kev sib xyaw ntawm phagosome thiab lysosome. Txhawm rau txhawm rau rhuav tshem cov kab mob, nrog rau cov kab mob pathogenic, nws yog ib qho tsim nyog yuav tau fuse lub phagosome nrog lysosome uas muaj hydrolytic enzymes. Lysosome tso nws cov ntsiab lus rau hauv phagosome. Qhov chaw sab hauv ua kua qaub vim yog cov ntsiab lus lysosome. Tom qab ntawd cov enzymes hydrolytic zom cov ntaub ntawv engulfed hauv phagolysosome. Tom qab kev zom zaub mov, cov khoom siv tau raug hloov mus rau cytoplasm ntawm lub cell thaum lwm yam tshuaj raug tshem tawm ntawm lub cell los ntawm exocytosis.
Phagosome yog dab tsi?
YA phagosome yog ib qho vesicle tsim thaum phagocytosis. Thaum ib tug phagocyte ntsib cov khoom uas nyob ze nws, nws invaginates nws plasma membrane thiab nyob ib ncig ntawm cov khoom, tsim ib vesicle.
Daim duab 01: Phagocytosis
Vim lub vesicle yog ib feem ntawm phagocytic cell, nws yog hu ua phagosome. Phagosomes paub tab ua ob peb kauj ruam. Thaum ib tug phagosome buds tawm hauv lub cell, nws ua ib tug nascent phagosome. Tom qab ntawd nws loj hlob mus rau hauv ib qho phagosome thaum ntxov thiab tom qab ntawd mus rau hauv phagosome lig. Tom ntej no, nws fuses nrog lysosome los tsim phagolysosome.
Dab tsi yog qhov zoo sib xws ntawm Phagolysosome thiab Phagosome?
- Ob leeg phagosome thiab phagolysosome muaj nyob hauv phagocytic cells.
- Lawv yog ob lub qauv tsim thaum lub sijhawm phagocytosis.
- Ob leeg yog daim nyias nyias nyias.
- Cov engulfed particles muaj nyob rau hauv ob hom vesicles.
- Ob leeg phagolysosome thiab phagosome yog qhov tseem ceeb hauv kev engulfing thiab rhuav tshem cov kab mob phem.
- Cov hom hlwv no ploj tom qab kev puas tsuaj ntawm cov kab mob.
Qhov txawv ntawm Phagolysosome thiab Phagosome yog dab tsi?
Phagolysosome yog ib lub vesicle tsim los ntawm kev sib koom ua ke ntawm phagosome thiab lysosome thaum phagosome yog ib lub vesicle tsim los ntawm phagocytic cell engulfing khoom khoom. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phagolysosome thiab phagosome. Phagolysosome muaj ob qho tib si engulfed cov ntaub ntawv thiab lysosome cov ntsiab lus, thaum phagosome tsuas muaj cov ntaub ntawv.
Ntxiv mus, phagolysosome yog qhov tseem ceeb txhawm rau txhawm rau zom cov ntaub ntawv engulfed, thaum tsim ntawm phagosome yog qhov tseem ceeb txhawm rau txhawm rau nqa cov teeb meem hauv lub cell. Lwm qhov sib txawv ntawm phagolysosome thiab phagosome yog phagolysosome yog microbicidal vim nws muaj hydrolytic enzymes thaum phagosome tsis microbicidal.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm phagolysosome thiab phagosome hauv daim ntawv tabular.
Summary – Phagolysosome vs Phagosome
Phagosome thiab phagolysosome yog ob hom vesicles pom thaum phagocytosis. Phagolysosome yog ib qho cytoplasmic vesicle tsim los ntawm kev sib xyaw ntawm phagosome nrog lysosome. Lub phagosome yog ib lub vesicle tsim, engulfing cov ntaub ntawv uas tau tuaj ze ntawm lub phagocytotic cell. Thaum lub phagosome yog tsim, nws fuses nrog ib tug lysosome uas nqa hydrolytic enzymes. Hydrolytic enzymes yog qhov tseem ceeb txhawm rau txhawm rau zom cov khoom siv, suav nrog cov kab mob pathogenic. Yog li, phagolysosome yog microbicidal vim nws muaj hydrolytic enzymes, tsis zoo li phagosome. Yog li, qhov no xaus cov ntsiab lus ntawm qhov sib txawv ntawm phagolysosome thiab phagosome.
